Open champion Cameron Smith claims golf's world rankings are becoming "obsolete" due to there being no points awarded for LIV Golf tournaments.

The Australian spoke out ahead of this week's Saudi International, an Asian Tour event that was getting under way on Thursday, saying it hurt him that his prospects of getting to number one had been dealt a blow.

Smith is among a host of major winners and star names who have defected from the PGA Tour and DP World Tour to the controversial LIV Golf tour, a lucrative Saudi-backed series that critics claim was launched in an effort to 'sportswash' the Middle East country's reputation.

For 29-year-old Smith, who won the Chicago leg of the LIV series last September, the limitations of where he can collect ranking points is a setback. He has been as high as number two but is now fourth on the rankings list, which is led by Northern Ireland's Rory McIlroy.

McIlroy has been as vociferous an opponent of LIV Golf as any player and is not playing this week in Saudi Arabia, where a host of top names, many of them from LIV Golf, are in the field and ranking points are available.

Smith said of the rankings situation: "I've tried to take it not that badly. When you rock up to a tournament, you know who you have to beat, whether there's a world ranking or not. There's generally seven or eight guys that are in that field that you know are going to put up a pretty good fight.

"For sure it hurts. I feel as though I was really close to getting to number one, and that was definitely something I wanted to tick off, but the longer that this stuff goes on, I think the more obsolete those rankings become.

"That's just the long and short of it, I think. Do we need them? It would be nice, but like I said, you know who you've got to beat when you get on the golf course."

LIV Golf is hoping it will be able to award ranking points in future.

Smith said he had enjoyed parading the Open Championship's Claret Jug while at home during the off-season.

"I took it back down to Australia, took it to my home club," he said. "They actually had a trophy night, kind of the day that I got back down there, so I took it to the trophy night.

"It was a little bit hectic. It's a pretty cool trophy. I'd describe it as like seeing a ghost, I think, for the most part, the look that it brings to their face and the feeling that it gives them is pretty special.

"I've taken it everywhere with me. Just about had every liquid you can put in there I've tried to put in it. But it's been awesome. It's been fun over Christmas; the family drinking out of it was something I'll never forget."

Head coach Mike McCarthy will take over play-calling duties for the Dallas Cowboys next season, it has been confirmed.

The shift in responsibilities comes after the departure of offensive coordinator Kellen Moore, who left at the start of this week and has joined up with the Los Angeles Dodgers.

His exit followed the departures of six others, including assistant head coach Rob Davis and offensive line coach Joe Philbin, in the wake of the Cowboys struggling offensively in a 19-12 loss to the San Francisco 49ers in the Divisional round game.

McCarthy's evolving role had been anticipated and was verified by team owner and general manager Jerry Jones and executive vice-president Stephen Jones on Wednesday.

Jerry Jones said: "This is the logical step to build on it and use what we've established, if you will, the foundation of the things we've got. This is the time for us to build on it. That's what this is, a building step."

The Cowboys finished the 2022 regular season ranked fourth in the NFL in scoring (27.5 points per game) and 11th in total offense (354.9 yards per game), but the team managed just 282 total yards and one touchdown in the loss to the 49ers.

Dallas have not advanced past the Divisional round of the playoffs since winning the Super Bowl following the 1995 season.

Quarterback Dak Prescott had a career-worst 15 picks over the season, and Stephen Jones called for sweeping changes to be made, saying: "Sometimes in order to take the next step, you have to get uncomfortable.

"Sometimes for Dak to take the next step, he might have to get uncomfortable and do something different.

"For Mike to take the next step, he’s got to do something different. For us to take the next step, same thing.

“If you keep doing the same thing over and over again and expect different results, good luck."

Denver Nuggets head coach Michael Malone and his staff will take charge of LeBron James' team in this season's All-Star Game.

The game will be played in Salt Lake City on February 19, with LeBron's team taking on a side headed up by Giannis Antetokounmpo of the Milwaukee Bucks.

A victory for the Portland Trail Blazers over the Memphis Grizzlies on Wednesday ensured the Nuggets will top the Western Conference by the end of play on Sunday, two weeks before the game, meaning Malone's coaching staff are assured of their roles in the exhibition event.

It is the second time in his career that Malone will coach in the All-Star Game, after he oversaw a 178-164 victory for Team LeBron over Team Giannis in 2019. Joe Mazzulla, interim coach of the Boston Celtics, is to take charge of Team Giannis.

The Nuggets still have eight games to play before the All-Star break, however, starting with a clash against the Golden State Warriors on Thursday, and Malone warned against any complacency.

He said: "I say it every year and I told our players this. There's some teams that are dying for the All-Star break and can't wait to go to Cancun.

"No, we are keeping our eyes on the prize and we have to make sure we play all the way to the break."

Nuggets star Nikola Jokic has been selected as a starter, though the two-time reigning NBA MVP might not be coached by Malone, who will have to wait until the day of the game to find out his full roster when James drafts his side.

The 2022 Six Nations may have proved to be a battle between the haves (France and Ireland) and the have-nots (England, Scotland, Wales and Italy), but this year's tournament is expected to be a far tighter affair.

France ended a 12-year wait for the title last time around, while claiming a record-equalling fourth Grand Slam, and they will fancy their chances of coming out on top again this year ahead of hosting the Rugby World Cup in September.

Ireland, who narrowly missed out to Les Blues 11 months ago, will have plenty to say about that as they look to continue building the momentum that saw them record a famous series win over New Zealand and climb to the top of the world rankings.

Both nations, ranked as they are as the world's top two as we edge closer to the World Cup, will very much have a target on their backs as the other contenders look to lay down a marker.

It is a time of change for England and Wales, who have brought in Steve Borthwick and Warren Gatland respectively on the back of disappointing campaigns last time out, with this year's Six Nations representing a first opportunity to see their sides in action.

While Italy would often be a side note heading into the competition – justifiably given they have finished bottom in each of the past seven editions – they ended a long-running winless streak with victory over Wales last year, which they followed up with a win against Australia three months ago.

And don't forget Scotland, who themselves came close to a historic win against New Zealand in November and finished level on points with fierce rivals England in last year's Six Nations.

Unfavourable fixtures for France

France are looking to do something not achieved since England in 2017 in retaining the Six Nations title, while not since 1998 – prior to Italy joining to make it a six-team tournament – has a nation won successive Grand Slam crowns, with Les Blues themselves the last to do so.

Despite being reigning champions and in great form with 13 wins in a row, even those with strong French ties are wary of the threat a strong Ireland side pose.

"I don't want to downplay it at all, but we're not the best team in the world – Ireland are, and that's just a fact," 47-cap former France international Ben Keyser told Stats Perform.

"We are title holders, but we've fallen on our faces previously when we've entered the tournament as favourites. This year we've got to go to Ireland and England, so it's going to be a really tough year for France."

That trip to Irish capital Dublin in the second round may yet prove to be a showdown for the championship, as it was last year when the only blemish for Andy Farrell's men was a defeat in Paris.

It must be remembered, however, that Ireland were also top of the world rankings heading into the 2019 World Cup, when they suffered defeat to Japan in the pool phase before being knocked out by New Zealand in the quarter-finals.

'Wales way behind'

Before thoughts can turn to that huge match with France, and indeed the World Cup even further down the line, Ireland first have an away trip to Wales in what will present a chance to lay down a marker in their bid to land a first Six Nations title since 2018.

On the back of Gatland's shock return as Wales boss following the sacking of Wayne Pivac, though, all of a sudden Saturday's curtain-raising clash at the Principality Stadium looks nowhere near as clear-cut to predict.

"A month or two ago I'd have said that's going to be a tough one because it's Cardiff, but Wales are in a bit of disarray and it's hard to see how they're going to beat this Ireland," former Ireland and British and Irish Lions hooker Rory Best told Stats Perform.

"But all of a sudden there's a change at the helm and all of a sudden you're a lot more worried about this game in Cardiff. You know their style of play and you know Gatland will make them hard to beat. That makes this a potential banana skin for Ireland."

Former Ireland boss Gatland needs no introducing, having won the Six Nations four times during his previous 12-year stint in charge of Wales, three of those as Grand Slam winners.

Indeed, he has been involved in 60 Six Nations games during his time with Ireland and Wales, which is the same tally as the other five head coaches in this year's championship combined.

That experience and ability to get the best out of a squad will come in handy for Wales as they attempt to recover from a terrible 2022 that saw them lose at home to Italy and Georgia.

Making the leap from fifth to first is likely to be out of the question, but exactly what would represent a positive campaign for Wales with one eye on the upcoming World Cup?

"Third. Coming third would be good," Wales great and former skipper Sam Warburton told Stats Perform. "That sounds really defeatist because normally you'd always aim to win it, or finish second, but I'm being realistic.

"Ireland and France are putting on displays which have had four or five years of groundwork. Wales are coming into the tournament not entirely fresh, but pretty close to that. So naturally they're way behind where those teams are in their cycle."

Borthwick to get the best out of England?

Finishing third would be a case of 'best of the rest' when up against the world's top two sides, but recently appointed England head coach Borthwick will quietly be hoping to challenge for the title.

Unlike Gatland, this will be Borthwick's first taste of Six Nations action as a head coach, though he did play 25 times in the championship as a player, 10 of those as captain of his country.

While Eddie Jones' tenure turned sour, his sacking on the back of a tough autumn campaign still came as somewhat of a surprise, but the now-Australia boss still departed with the best record of any England head coach.

Indeed, Jones won the Grand Slam in his first Six Nations campaign in charge in 2016, so there is recent precedent there for Borthwick – who previously worked as Jones' right-hand man – to follow.

In the view of former captain Chris Robshaw, the Red Rose have plenty to be optimistic about with Borthwick at the helm.

"Steve coming in is a brilliant appointment," Robshaw told Stats Perform. "You just look at the team he's created around him, such as Kevin Sinfield in defence, and the change in mindset. 

"I think they've got a fantastic team and a group that's in a nice age bracket, with a couple of younger players who can add some spark and bring some life back into the side. What I'm seeing and hearing are good messages with a lot of excitement."

'Toughest Six Nations yet'

Not for the first time, Scotland head into the Six Nations with a rather big question mark over their head. As ever, consistency will be the key if they are to better last year's fourth-place finish.

The additions of Ben Healy and Ruaridh McConnochie, who previously represented Ireland and England respectively, will provide some welcome depth for Gregor Townsend to choose from in possibly his final campaign in charge.

Both men may feature in a blockbuster opener for Scotland at Twickenham, where they picked up a first win since 1983 on their most recent visit, albeit with that game held behind closed doors due to the coronavirus pandemic.

Saturday's Calcutta Cup contest may well provide a better indication of exactly what the aim is for Scotland this time around.

"You never really know what to expect from them and that's exciting," Robshaw added. "That's why the Six Nations is brilliant, because anyone can beat anyone. It's why every day you have to be on it; if you're not you lose a game by the bounce of a ball and all of a sudden you're playing catch up.

"I think this year is going to be the toughest Six Nations yet. I don't think it'll be a Grand Slam year."

Robshaw will certainly not be alone in predicting a non-Grand Slam year, with teams expected to take points off each other, but what about at the other end of the table?

Perennial Wooden Spoon 'winners' Italy have finished bottom in every edition since 2016, but their aforementioned wins over Wales – ending a 36-game losing run in the competition – and Australia last year sent out quite the message.

Having avoided losing all five games for the first time in seven years last time around, the aim for the Azzurri now is to finish above one of the other five nations.

It all paves the way for what could be the best Six Nations in a number of years – certainly since the most recent World Cup – as new eras begin and some perhaps edge towards their pinnacle ahead of the Rugby World Cup in seven months' time.

Boston Celtics' Robert Williams says team-mates Jayson Tatum and Jaylen Brown are using last year's close call as motivation to win the NBA Championship this time around.

Tatum and Brown were scintillating as the Celtics cruised to an emphatic 139-96 victory over the Brooklyn Nets on Wednesday.

The duo became the first team-mates in franchise history to each make seven three-pointers in the same game, doing so in just three quarters, while Tatum's plus-42 heading into halftime saw him better Kevin Garnett's Celtics record for a single-half plus/minus.

Tatum finished with a game-leading 31 points as well as nine rebounds and four assists, while Brown had 26 points, three assists and three rebounds. It was the eighth time this campaign that the pair have each accumulated 25 points or more.

Williams added a useful 16 points and nine rebounds from just 19 minutes of action, and he said Tatum and Brown are "carrying the team" as they look to make amends for last year's NBA Finals defeat to the Golden State Warriors.

"They take all criticism. They take all the 'he said, she said'," Williams said.

"But I love how they've been responding. Feel like they're hungry, really. You know what I'm saying? Still p***** about last year."

Only Luka Doncic of the Dallas Mavericks (1,538) has more points on the board than Tatum's 1,493 this season, while the latter's 31.1 points per game average is a career-best.

Tatum, for his part, feels the sustained level of performance from Brown and himself has been overdue as he noted "it's not done" until the Celtics clinch their first championship since 2008.

He told reporters: "It's been a long time coming. We've had our good times and not-so-good times, but I think those are just growing pains.

"We were just 19-year-old kids that came into the league hungry and trying to help our team win. We've had to learn how to play in this league, learn how to play with each other, learn how to lead the team.

"I feel like we're still a long way ultimately from where exactly we want to be, but we've made amazing strides from the beginning.

"You can tell we were ready to go from the jump. We've still got a long way to go. It's not done until we win a championship."

It was the first time in franchise history that Boston, who top the Eastern Conference with a league-best 37-15 record, outscored their opponent by at least 30 points in the first quarter, in which they scored 46 points before going on to record their biggest victory of the season.

Nets star Kyrie Irving, whose 20 points was a team-high for Brooklyn, felt there was little his side could do as they slumped to their heaviest loss since a 44-point defeat to the Portland Trail Blazers in February 2014.

"It's clear as day that they want to win the championship, and they're not wasting any time in the regular season," Irving said. "Tonight I felt like we were just one of those teams in the way, and you know, we just can't be one of those teams in the way.

"We've got to be one of those teams that stands up to them and at least shows them that we're going to be competition for them moving forward, which I believe we are. But we just didn't show it."

The Brooklyn Nets fell to their worst loss in nine years after a hugely one-sided first quarter teed the Boston Celtics up for a 139-96 win.

The Nets had lost their previous two games against the Celtics this year, but this was by some margin the worst of the lot.

A 43-point loss was the Nets' heaviest since losing by 44 against the Portland Trail Blazers in February 2014.

Brooklyn never gave themselves a chance after being outscored by 30 in the first quarter, shooting one of 12 from the field to start as shot after shot went in at the other end.

The Nets' 23.1 per cent three-point shooting over the game stood in stark contrast to the Celtics' 48.1 per cent as Jayson Tatum (31 points) and Jaylen Brown (26 points) made seven threes apiece.

The pair were the first Boston team-mates to each make seven threes in the same game in franchise history, and the huge lead even allowed them to sit the fourth quarter.

Former Celtic Kyrie Irving was one of seven from beyond the arc on his way to 20 points and a plus/minus of minus-31.

No let-up from Lillard

Another big performance from Damian Lillard saw Portland rally to beat the Memphis Grizzlies 122-112.

Lillard scored 42 points, including a stunning seven-point play early in the third quarter, along with his 10 assists and eight rebounds.

The point guard has now topped 30 points in five straight games as the Blazers have gone 4-1 and 11 of 13 games going back to early January.

Swift revenge for Sixers

The Philadelphia 76ers had suffered a shock loss in their previous game at home to the Orlando Magic two days earlier, but a rematch went according to plan.

Joel Embiid, the bright spot in that loss, was again influential with 28 points and 11 rebounds in a 105-94 win.

Markelle Fultz, Embiid's former Sixers team-mate, had celebrated victory on his first return to Philadelphia and again tried to lift the Magic in this loss, finishing with a team-high 18 points on seven-of-11 shooting.

Hall of Fame NFL executive Bobby Beathard has died at the age of 86.

Beathard spent more than three decades as an executive in the league, enjoying 10-year stints as general manager in both Washington and San Diego.

Beathard contributed to four Super Bowl successes overall, overseeing Washington's victories at Super Bowl XVII and Super Bowl XXII as GM, as well as helping the Miami Dolphins to two triumphs during a spell as director of player personnel.

The 2018 Pro Football Hall of Fame inductee died aged 86 on Monday as a result of complications arising from Alzheimer's disease.

A statement from the Washington Commanders read: "Bobby was a man of extraordinary class and integrity and was the architect behind the greatest teams in this organisation's history.

"He cared deeply about everyone he worked with and always put the team first. Bobby is rightfully enshrined in both the Pro Football Hall of Fame and Washington Ring of Fame and will go down as one of the greatest executives in NFL history."

Beathard's grandson, quarterback C.J. Beathard, played in four games for the Jacksonville Jaguars during the 2022 season, having entered the league with the San Francisco 49ers in 2017.

Philadelphia Eagles reserve offensive linesman Josh Sills has been indicted on rape and kidnapping charges from an alleged 2019 incident in Ohio, authorities said on Wednesday.

Sills engaged in alleged sexual activity that was not consensual and held a victim against her will in December 2019, Ohio attorney general Dave Yost of Guernsey County said in a news release.

The case, which was immediately reported and investigated, was presented to the grand jury on Tuesday and is being prosecuted by the attorney general's office.

Sills, an undrafted free agent who has played just once this season, was ordered to appear in court in Ohio on February 16, four days after the Eagles' Super Bowl LVII clash against the Kansas City Chiefs.

"Sills may not participate in practices and games or travel with the team while on the Commissioner Exempt List," the NFL said in a statement.

"The matter will be reviewed under the NFL's personal conduct policy."

The Eagles added in a statement: "The organisation is aware of the legal matter involving Josh Sills. 

"We have been in communication with the league office and are in the process of gathering more information. We have no further comment at this time."

Sills, who played for West Virginia and Oklahoma State, was signed by the Eagles as an undrafted free agent in April.

It was a bad day for seeds at the Lyon Open, with Petra Martic and Mayar Sherif both crashing out in the round of 16 in France.

Fourth seed Martic made a good start against American opponent Alycia Parks on Wednesday, only to lose 2-6 7-6 (7-3) 6-2.

Sixth seed Sherif was more convincingly beaten as she fell to Czech teenager Linda Noskova 6-3 6-2.

Noskova will face Camila Osorio in the quarter-finals after the Colombian came out on top in a tight clash with Jule Niemeier 7-6 (7-5) 7-5

In the two remaining first-round matches, Jasmine Paolini defeated Rebeka Masarova 6-3 6-2, while Belgian Alison Van Uytvanck will face top seed Caroline Garcia in the last 16 after beating Tamara Korpatsch 6-2 6-4.

At the Thailand Open, it was not much better for seeded players as Anna Kalinskaya and Linda Fruhvirtova both exited on Wednesday.

Fourth seed Kalinskaya was overwhelmed 6-0 in the opening set against Lesia Tsurenko, only to win a tie-break in the second.

The unseeded Ukrainian ultimately won out, though, sealing a 6-0 6-7 (3-7) 6-4 victory to reach the quarter-finals.

Eighth seed Fruhvirtova also managed to level after falling a set behind, and also could not find the win as the 17-year-old was beaten by Tamara Zidansek 6-3 4-6 6-4.

The Slovenian will face Zhu Lin in the last eight after her straight-sets win over Jang Su-jeong, but there was one win for a seed as Xinyu Wang (seventh seed) beat Mirjam Bjorklund 6-3 6-3.

Kyle Shanahan has not yet decided which of Brock Purdy or Trey Lance will be the San Francisco 49ers starting quarterback moving forward – but it will certainly be one of them.

Purdy was one of the surprise stars of this 2022 NFL season, coming to the fore in his rookie year having been the final pick in the draft.

He led the 49ers to the NFC Championship Game, only to sustain an elbow injury against the Philadelphia Eagles that significantly hindered San Francisco in a one-sided loss.

Purdy only got his opportunity after Lance, selected third overall in 2021, and backup Jimmy Garoppolo were both injured.

When Purdy's own backup Josh Johnson suffered a concussion against the Eagles, the luckless 49ers had lost four QBs, leaving Purdy to play out the rest of the game without throwing the ball.

Coach Shanahan confirmed on Wednesday there was unlikely to be a return in 2023 for free agent Garoppolo, and the 49ers do not see the need for an alternative veteran starter.

But where that leaves Purdy and Lance remains unclear. Both men are injured with the aim of returning before next season; Purdy tore elbow ligaments, while Lance broke his ankle.

"I know we have two starters on our team right now that I believe we can win with," Shanahan said. "So, when you have that situation, you're not that eager to go looking around."

Purdy and Lance, speaking earlier in the week, each described their excitement to return to fitness and "compete".

Lance added to reporters: "I'm sure it will be a whole story again this year for you guys."

Wednesday's game between the Detroit Pistons and the Washington Wizards has been postponed due to weather-related travel issues.

The Pistons have been unable to get back to Detroit after Monday's defeat at the Dallas Mavericks, with an ice storm leading to several flights out of Dallas Fort-Worth International Airport being cancelled in recent days.

A weather warning will remain in effect until at least Thursday, with ice also affecting roads.

The Pistons said in a statement: "We will provide further information on the new date and time once it is available."

Detroit sit bottom of the Eastern Conference with a record of 13-39, while the ninth-placed Wizards are on a six-game win streak, currently 24-26 overall for the season.

According to ESPN's Adrian Wojnarowski, Thursday's game between the Mavericks and the New Orleans Pelicans is also in doubt due to the weather conditions.

Mick Schumacher has been named as McLaren's reserve driver for 2023 after a deal was struck with Mercedes.

The 23-year-old, son of Formula One great Michael Schumacher, lost his seat at Haas following the 2022 season and was subsequently released from Ferrari's young driver programme.

Schumacher signed as Mercedes' third driver, behind Lewis Hamilton and George Russell, but will now deputise for Lando Norris or Oscar Piastri at McLaren in the event of either being unable to race.

Those opportunities would still be presented should either Hamilton or Russell have issues this season, though there is now a greater chance of Schumacher making an appearance on the grid.

In two seasons at Haas, Schumacher scored points on two occasions from 43 races and was replaced by compatriot Nico Hulkenberg for the 2023 campaign.

As pointed out by McLaren, representing the team brings the Schumacher name full circle as team principal Andrea Stella worked alongside Mick's father as performance engineer.

The Tampa Bay Buccaneers have paid tribute to quarterback Tom Brady following his retirement after 23 years in the NFL.

The seven-time Super Bowl winner announced his retirement from the sport on Wednesday, bringing an end to a three-year spell in Tampa Bay.

His first year with the franchise resulted in Brady's final Super Bowl triumph and only the team's second all-time, which came after years of dominance with the New England Patriots.

The Buccaneers' Glazer owners issued a statement thanking Brady for his contributions, which read: "Tom's impact on our franchise these past three years has been immense and we are appreciative of the time we had with him here in Tampa Bay.

"He set an exceptional standard that elevated our entire organisation to new heights and created some of the most iconic moments in our history.

"Tom's impact will be felt within our community for many years to come and we will forever be grateful for those unforgettable memories that he provided during these final seasons of his legendary career.

"We wish him the best in this next chapter of life and are confident he will find similar success in his future endeavours."

Head coach Todd Bowles, who was defensive coordinator for the first two years of Brady's time in Tampa Bay, said: "I have always had the utmost respect for Tom Brady as a football player, as a winner and as a person.

"It wasn't until he joined us three years ago that I was able to truly appreciate him as a team-mate. Even before I became head coach, we communicated often and had a strong relationship built on mutual respect and a desire to win.

"That connection only grew over this past season as we fought to get the most out of our football team. I greatly appreciate the leadership he provided and I'm thankful for our time together."

General Manager Jason Licht, who brought Brady to the Buccaneers and has held his role since 2014, feels that the 45-year-old's impact will continue to be felt over the course of the coming years.

"Tom's legacy is unmatched in the history of this game," Licht said. "All the Super Bowl titles and statistical records speak for themselves, but the impact he had on so many people through the years is what I appreciate the most.

"His imprint on this organisation helped take us to the mountaintop. We will certainly miss him as our quarterback, but I will also miss him as a leader and friend.

"Our entire organisation is indebted to him for what he provided us over the past three years. We won't ever forget the wins or the accolades and his influence will be felt for years to come."
