Australia is the "preferred candidate" to host Rugby World Cup 2027 under revamped selection procedures announced Wednesday.

The World Rugby Council's move all but guarantees Australia will host the quadrennial event, but it will not be confirmed until a final vote is held next May. 

World Rugby bestowed the same "preferred" status on England to host the 2025 women's event and selected the United States for "exclusive targeted dialogue" for Rugby World Cup 2031. 

The new process follows the lead of the International Olympic Committee's adoption of a "preferred bid" model that led to Brisbane being awarded the 2032 Summer Olympics earlier this year. 

World Rugby said the system should help accelerate global growth and provide a more flexible approach for future hosts. 

"We must continue to keep up with the fast pace of change in our current world and provide value for our future host nations and unions," World Rugby chief executive Alan Gilpin said in a release. 

"Flexibility is a necessity to ensure good governance and to have successful sustainable men’s and women’s Rugby World Cups. We will do that while maintaining the personality of our events and our commitment to having players and fans at the heart of everything we do."

Australia last hosted the World Cup in 2003, with the hosts falling to Jonny Wilkinson and England in the final. 

"This is a huge step forward in our ambitions to host Rugby World Cup 2027 and for rebooting the game in Australia," Rugby Australia chairman Hamish McLennan said in a release. 

"Throughout this process, we've held the genuine belief the time was right to bring the Rugby World Cup back to our shores. The team at Rugby Australia have worked hard on this for a number of years and today's announcement is great reward for those efforts."

The 2023 event is set to be held in France. 

International players will be permitted to change allegiances, subject to meeting certain criteria, following the approval of the World Rugby Council.

The amendment to the sport's regulations governing national team representation will come into effect from January 1, 2022.

Following extensive discussions, the new process has been applied with the aim of benefitting players and the global competitiveness of rugby.

In order to meet the criteria, a player must either be born in the country to which they wish to transfer, or have a parent or grandparent who was born in that country.

Furthermore, a player hoping to make the switch must stand down from international rugby for a period of three years.

Players may only change union once and each case will be subject to approval by the World Rugby Regulations Committee in order to preserve integrity.

World Rugby chairman Bill Beaumont said: "Approval of this landmark regulatory change is the culmination of detailed and widespread modelling and consultation across the game. 

"We have listened to our membership and players and sought to update the regulation recognising the modern professional rugby environment without compromising the integrity of the international game.

"Any player who wishes to transfer will need to have a close and credible link to their new union, namely birth right or parent or grandparent birth right while meeting strong criteria, including a 36-month stand-down period. 

"We believe that this is the fairest way to implement progressive change that puts players first while also having the potential to support a growing, increasingly competitive international men's and women’s game."

Lewis Hamilton is hopeful that future team-mate George Russell will be the next Briton to win the Formula One world championship.

The British drivers will link up next season, with Russell set to replace Valtteri Bottas at Mercedes.

The 24-year-old is 15th in the drivers' standings, having achieved his first podium with Williams at the Belgian Grand Prix, while also recording top-10 finishes in Hungary, Italy and Russia.

Many expect Russell to offer a genuine challenge to Hamilton, who recently signed a new two-year deal with Mercedes, with the latter seeking an eighth world title and just eight points behind leader Max Verstappen heading into the final two races of the 2021 season.

The 36-year-old is anticipating a healthy rivalry with his compatriot and hopes he can be a positive influence on the 2018 Formula 2 world champion.

"You've seen George is hugely respectful," he said in an interview published by BBC Sport.

"He's a super-talented young man and I think there's a huge amount of respect already going in, and we've got a nice balance at the moment.

"But he's going to want to be quick, he's going to want to show up and win, and do all those things that you do when you enter a new role.

"I remember in 2007 when I went up against [Fernando] Alonso [at McLaren]. Of course, I wanted to beat him at the first race, so I appreciate and expect George to have that mentality; otherwise he's not a winner.

"But I'm in a different place. I really want to see him succeed. There's going to be a point where I don't continue in this sport. He's my team-mate, and he's going to be the next Brit that I want to see win a world championship.

"So, while we are going to be competing, and I want to win on track. I really hope I can have a positive influence on how he conducts himself within the team, whether it's the time he commits to engineering or how he churns through the data, or even just how he drives on track."

Lewis Hamilton is aiming to be the "smarter" driver as he bids to outrun Max Verstappen in a remarkably close Formula One title challenge.

Hamilton is hunting a record seventh world title, but currently trails Verstappen by eight points heading into the final two races of the season.

The 36-year-old has won the last two grands prix, however, having followed up his triumph in Sao Paulo with success in Qatar last weekend.

Hamilton and Verstappen's contest has regularly boiled over onto the track, the former penalised for a collision at Silverstone, while the latter was punished at the Italian Grand Prix and was fortunate to escape a penalty for a near-miss in Brazil.

"Rather than giving someone the benefit of the doubt, you have to know that's what's going to happen," Hamilton told BBC Sport.

"So you always have to be ready to avoid a collision at all costs, [even] if it means going wide, because you want to see the end of the race, right? If you're stubborn and you hold your ground, you're going to crash.

"So that's what I've just tried to do. You can't always get it perfect.

"I am not too big or too successful to have to back out to fight another day. I know that is sometimes the route you have to take. You have to be the smarter one.

"And sometimes you lose points in doing that, for sure, but it's not just about me. I have 2,000 people behind me and through that selfish decision I could make. That costs all my team potential bonuses at the end of the year, all the hard work they have to do, the damage of the car. I am conscious of those things also."

Hamilton believes driving, and winning, in as pure a fashion as possible is the best way for him to prove his quality.

"It's just how my dad raised me," said Hamilton. "He said to always do your talking on the track.

"I was bullied as a kid, both at school but also on track, and we wanted to beat them the right way, not by a car falling off or colliding.

"Then, there is no denying that you're better. I want to be the purest of drivers, through speed, through sheer hard work and determination, so there's no denying at the end what I've accomplished."

Of Verstappen's aggressive approach, Hamilton said: "He's not the only driver I've raced against that's like this.

"I've raced so many drivers in my time and they've all been very different in the way they behave. And it's interesting.

"Now I'm older, I look a little bit deeper into their character and a bit of their background, upbringing. Our upbringing is why we act out the way we do and behave the way we do, good or bad. So I try to understand those so I can have more appreciation of who that character is I am racing with."

The Los Angeles Lakers were without suspended superstar LeBron James and not even a Russell Westbrook triple-double could fuel the title hopefuls as they were beaten 106-100 by the New York Knicks.

James was not on the court because of a ban handed down – the first of his illustrious career – for his ejection against the Detroit Pistons, the four-time NBA champion struck Isaiah Stewart in the face and drew blood, sparking a melee.

Since James joined the Lakers in 2018, the team had been averaging 113.0 points and with a winning percentage of 64.6 when he plays heading into the matchup, while averaging 107.4 points with a 39.7 winning percentage when he does not.

In his absence, former MVP Westbrook had 31 points, 13 rebounds and 10 assists but the Lakers still lost on the road against the Knicks on Tuesday.

Westbrook posted 18 points in the third quarter to tie the game after the Lakers (9-10) had fallen in a 25-point hole, however, the Knicks recovered to beat the storied franchise for the ninth time in 11 games.

Anthony Davis put a pre-game illness aside to battle for 20 points, six rebounds and three assists in 34 minutes.

Julius Randle inspired the Knicks (10-8) with 20 points, 16 rebounds and five assists, while Evan Fournier contributed a team-high 26 points.

Porzingis achieves career first as Mavs win

For the first time in his career, Kristaps Porzingis (30 points) scored 20 or more points in seven straight games after helping the Dallas Mavericks trump the Los Angeles Clippers 112-104 in over-time.

Denver's slide continues as Jokic sits out again

Reigning MVP Nikola Jokic missed his third straight game due to a right wrist sprain and the Denver Nuggets went down 119-100 to the Portland Trail Blazers. The Nuggets have lost five consecutive games – their worst run since a five-game skid in January 2017.

The number one pick in the NBA Draft, it is safe to say Cade Cunningham's rookie season has been a baptism of fire. The first-year Pistons teenager has been criticised for his performances. In a 100-92 loss to the Miami Heat, he was just two-of-10 shooting – making one of seven three-pointers – for six points in 29 minutes, while he had four turnovers.

Los Angeles Lakers star Anthony Davis said he was surprised by the NBA's decision to ban superstar team-mate LeBron James for the elbow that sparked wild scenes against the Detroit Pistons on Sunday.

James jostled with Pistons center Isaiah Stewart at a free throw, with the four-time MVP's left elbow connecting with the latter's face, leaving him bleeding from his right eye and incensed.

Stewart initially appeared calm but lost control, repeatedly charging at James for retribution on court, having to be restrained by team-mates and coaches in Detroit's 121-116 defeat.

The Pistons big man was handed a two-game suspension for his actions, but James was also slapped with a one-game ban for the first time in his illustrious 19-year NBA career after "recklessly hitting Stewart in the face and initiating an on-court altercation".

"I was surprised," Davis told reporters after the Lakers went down 106-100 to the New York Knicks without James on Tuesday.

"I didn't think he was gonna get suspended. I don't think anyone thought he was gonna be suspended to be honest.

"It was an accident. He accidentally hit him in the face. The report came out and said his hit to the face caused an incident. He can't control how a guy is going to react.

"Guys get hit in the face all the time, we're saying that caused the incident? I get hit in my face, I probably won't hit anyone. If I go off and do all that, does the other guy get suspended? It was strange but nothing we can do about it."

Davis had his own drama on Tuesday, making a mad dash to arrive at Madison Square Garden less than an hour before tip-off due to illness, playing 34 minutes for 20 points, six rebounds and three assists.

Lakers head coach Frank Vogel said Davis seemed a "little bit drained" although the NBA champion refused to blame that for the defeat which left the franchise 9-10.

"I don't use my illness as an excuse," Davis said. "I go out there and give it my all. I think we were tied in the fourth. we missed some shots."

After the Lakers fell short despite Russell Westbrook's triple-double, Davis added: "I just woke up not feeling well. Headache, flu symptoms, coughing, fever, body aching, everything. I was in my hotel waiting for my fever to break.

"It was a low-grade fever. I couldn't leave until my fever broke. My fever broke, got in the car and shot straight here. [I arrived] 46-48 minutes from the game clock. I got in and did as much as I can treatment wise, got dressed, went out to play."

Klay Thompson is back in full-team practice for the first time in more than two years and believes his return can help the Golden State Warriors win the NBA title.

Thompson was a key member of championship-winning teams in 2015, 2017 and 2018 but sustained an anterior cruciate ligament (ACL) tear as the Warriors' 'three-peat' bid failed against the Toronto Raptors in the 2019 Finals.

The guard then suffered an Achilles tendon injury while recovering, meaning he missed the entirety of two seasons prior to 2021-22.

But Thompson is now close to his long-awaited return, with his 19.5 career points per game and 41.9 per cent three-point shooting set to boost a Warriors team already leading the league.

Back practising alongside his team-mates on Tuesday, Thompson said: "It's so exciting. Just to be running up and down the court and playing basketball, it's truly a blessing and it makes coming to work so easy.

"The boring stuff's behind me and now it's just getting back in game shape. I've got to stay patient because I can be an overeager person to get out there and play, but I'm just incredibly grateful to be out there.

"The work the training staff and I have done over the last two years is really paying off, and it's hard to put into words how grateful I am to be playing basketball again."

After two tougher years following Thompson's injury and Kevin Durant's departure, Golden State are an outstanding 15-2. Only in 2015-16, when they had won each of their first 17 games, have the team enjoyed a better start.

The need for Thompson to return is not as desperate as had been imagined, as Stephen Curry is averaging 28.4 points in an MVP-calibre season while Andrew Wiggins (19.1) and Jordan Poole (18.4) have each also provided consistent scoring.

But adding Thompson into the mix is only going to improve the Warriors' chances, the man himself believes.

"We're 15-2. That's a great indicator of [being able to win a title]," he said.

"And our defence, I think it's top three in the league [allowing 101.1 points per game, ranked first], as well as our offense [scoring 114.2 points per game, also ranked first] – and I'm not even out there yet. Think about that. Really think about that.

"I'm more motivated than ever as well. I want a championship so bad. More than anything."

Warriors head coach Steve Kerr will not rush back his most reliable second man, though, explaining: "We don't have a target date.

"What we have is a number of weeks ahead of us for certain where we're going to play it out, keep letting him scrimmage as often as possible so that he'll build that endurance.

"And I would think within a few weeks we'll be able to finally sort of get a target date, but we don't have one right now."

China has called for people to stop "deliberately and maliciously hyping up" the Peng Shuai saga.

Two-time grand slam doubles champion was reported to have been missing since making sexual assault allegations against Zhang Gaol, the ex-vice premier and member of the Chinese Communist Party's Politburo Standing Committee, more than three weeks ago.

The Women's Tennis Association (WTA) welcomed pictures that showed Peng on a video call with International Olympic Committee (IOC) president Thomas Bach, but say the images do not alleviate its concerns about her wellbeing.

According to the IOC, Peng said she is "safe and well" in the call on Sunday and the 35-year-old spoke to president Bach for half an hour.

Despite footage released by Chinese state-run media on Saturday purporting to show Peng in a restaurant with friends, followed by images of her at a youth tournament on Sunday, concerns have continued to be raised regarding her safety.

Serena Williams, Naomi Osaka and Novak Djokovic are among many fellow players to have issued a plea for answers over Peng's whereabouts.

Human rights group Amnesty International stated the IOC is "entering dangerous waters" by taking part in a call with Peng and "should be extremely careful not to participate in any whitewash of possible human rights violations."

There was a firm message from China's foreign ministry on Tuesday, declared the issue is "not a diplomatic matter".

"I believe you have all seen that she recently attended some public events and had a video call [with IOC president Bach]," spokesman Zhao Lijian told reporters.

"I think some people should stop deliberately and maliciously hyping [the issue] up, let alone politicise this issue."

Ash Barty has announced her engagement to Liverpool fan and golfer Garry Kissick, capping a memorable year in style.

Barty added another sparkler to her collection when she revealed an engagement ring on Tuesday, having already landed the glistening Wimbledon trophy and an Olympic medal in the 2021 season.

She posted a picture of herself and Kissick on Instagram, showing off her ring and captioning the shot "Future Husband".

Kissick is a trainee professional at Brookwater Golf Club, a venue close to Brisbane, and is often seen in a Liverpool Football Club shirt, as was the case with the engagement picture.

He and Barty have visited Liverpool's home ground of Anfield together.

Speaking about having the likes of Kissick and coach Craig Tyzzer with her on the road, Barty said during her run to the Wimbledon title in July: "It's nice to be able to share some of these awesome moments with those that put so much time and energy into my career and allow me, encourage me, help me kind of work and figure out a plan and a way that they try and achieve our dreams. I think being able to share that with them is really special."

Barty won a bronze in mixed doubles at Tokyo 2020 alongside long-time friend John Peers, describing that achievement as "a dream come true".

She also won the Yarra Valley Classic, the Stuttgart Open, and WTA 1000 titles at Miami and Cincinnati before calling time on her season after a third-round exit from the US Open, where she lost to Shelby Rogers.

Barty finished the season as world number one for a third successive year, despite her recent inactivity.

She said a major triumph in her homeland was a priority for 2022, saying: "My focus is now on the Australian summer and doing everything I can to win the Australian Open. I can't wait to play at home again."

The Memphis Grizzlies scored the final seven points of the game for a stunning 119-118 road defeat of the Utah Jazz on Monday.

After Bojan Bogdanovic made a pair of three-pointers to give Utah a 108-112 lead with 1:28 to play, Ja Morant and Jaren Jackson Jr. combined to make four free throws and Jackson hit the go-ahead three-pointer with 5.7 seconds to play as Memphis (9-8) pulled out the win.

Utah (11-6) missed their final four shots of the game and also turned the ball over twice in the final 20 seconds. 

Morant had 32 points to lead all scorers and added seven assists, while Desmond Bane scored 28 and Jackson finished with 26. 

Bogdanovic led the Jazz with 24 points and Rudy Gobert contributed 23 on nine-of-10 shooting while grabbing a game-high 13 rebounds and blocking five shots. 

Durant, Nets hold off Cavaliers

Kevin Durant had 27 points and nine rebounds while James Harden chipped in 14 points and 14 assists for the Brooklyn Nets in a 117-112 road victory over the Cleveland Cavaliers. LaMarcus Aldridge added 21 points on 10-of-14 shooting off the bench for Brooklyn (13-5) as Darius Garland led Cleveland (9-9) with 24 points and 11 assists as he made only nine of 27 shots from the field. 

Tyrese Maxey scored 24 and Andre Drummond collected 23 rebounds as the Philadelphia 76ers (10-8) pulled away in the fourth quarter for a 102-94 defeat of the Sacramento Kings (6-12) despite playing without Joel Embiid, Tobias Harris and Seth Curry. De'Aaron Fox led the Kings with 23 in Alvin Gentry's first game as interim head coach. 

Jaylen Brown scored 19 points in 23 minutes as he returned to the Boston Celtics lineup after missing the previous eight games with a right hamstring strain. Jayson Tatum led all scorers with 30 as the Celtics (10-8) defeated Houston 108-90, sending the Rockets (1-16) to their 15th consecutive loss as they fell to 0-11 on the road. 

The Phoenix Suns held off a late charge by the San Antonio Spurs to prevail 115-111 for their 13th consecutive win. Devin Booker had 23 points to lead the Suns (14-3) while Deandre Ayton added 21 points and 14 rebounds. 

Bulls draw blanks from field

The Chicago Bulls entered Monday level with the Nets for the best record in the Eastern Conference but could not find their shooting touch in an ugly 109-77 home defeat against the Indiana Pacers. The Bulls (12-6) made 31 of 85 shots from the field (36.5 per cent), including just six of 28 (21.4 per cent) from three-point range. They scored 30 points in the second quarter but just 47 in the other three combined as Indiana (8-11) built an earl lead, then ran away with it in the second half. 

It took Jaylen Brown a while to get heated up Monday in his first game in two and a half weeks, but the Boston Celtics liked what they saw once he got going. 

Brown returned to the Boston lineup after missing eight games with a right hamstring strain and did his part as the Celtics pulled away from the woeful Houston Rockets in the second half for a 108-90 victory. 

Head coach Ime Udoka said before the game that Brown likely would be limited to 24 minutes, and he ended up playing 23, scoring 19 points on six-of-13 shooting from the field. 

The 25-year-old guard missed his first three shot attempts before sinking a jumper midway through the first quarter, but he did not show signs of his usual self until the second half. 

Midway through the third quarter, Brown embarked on a personal 10-0 run capped by a pair of three-pointers just 24 seconds apart to boost the Boston lead to 72-50. 

"He got warm, then got on that flurry in the third quarter," said Udoka. "To have him back in that third quarter to see what he did was a great sign."

Udoka said Brown "still doesn't feel normal, normal" so the team likely will take care to avoid rushing him back to his typical load of about 36 minutes per game. 

Any contribution figures to be a positive for the Celtics, who have now won three in a row for the first time this season as Jayson Tatum led all scorers with 30 points Monday.

All of the Celtics' big-picture plans include Brown as a key piece, though, so seeing him back on the court was a relief. 

"Once he was able to get a couple baskets, you could just see that he felt more comfortable with everything and he opened up," said team-mate Al Horford. "He's such a good player that he'll find his way."

Robert Williams III also returned to the Boston lineup after missing three games with a knee injury. The big man attempted just one shot from the field, and made it, but made his presence felt by racking up 15 rebounds. 

Alex Rodriguez and David Ortiz are among the newcomers on the ballot for the Baseball Hall of Fame's Class of 2022, which was announced Monday by the Hall.

Their arrival coupled with 2022 being the last year on the ballot for Barry Bonds and Roger Clemens guarantees questions about how the game should grapple with the legacy of performance-enhancing drugs will remain at the forefront for another election cycle.

Ten-year members of the Baseball Writers' Association of America (BBWAA) can vote for up to 10 of the 30 players on this year's ballot, and a candidate must receive at least 75 per cent of the votes to be elected. Results will be announced on January 25. 

The BBWAA did not elect anyone last year, with Curt Schilling coming the closest at 71.1 per cent followed by Bonds (61.8) and Clemens (61.6). 

All three will be in their 10th and final year on the writers' ballot, along with Sammy Sosa. 

Bonds, Clemens and Sosa have seen their candidacies stall thanks in part to long-standing rumours of PED use, and Rodriguez and Ortiz could face similar hurdles. 

Unlike the others, Rodriguez was suspended for violating MLB's drug policy, missing the entire 2014 season, while Ortiz reportedly was among the players who tested positive during unofficial survey testing in 2003. 

Voters will have to weigh that against their impressive on-field accomplishments. Rodriguez is one of the best hitters the game has ever seen, a three-time American League MVP and 14-time All-Star whose 696 home runs and 2,086 RBIs rank fourth in baseball history. 

Ortiz was a 10-time All-Star who led the Boston Red Sox to three World Series titles after a decades-long drought for the franchise and remains one of the most beloved figures of his era. 

Other first-time players on the 2022 ballot include longtime first baseman Mark Teixeira, 2007 National League MVP Jimmy Rollins, 2006 AL MVP Justin Morneau, 2007 NL Cy Young Award winner Jake Peavy and the man who won that award the next two seasons, Tim Lincecum. 

Closers Joe Nathan and Jonathan Papelbon, catcher A.J. Pierzynski, speedy outfielder Carl Crawford and slugger Prince Fielder also are on the ballot for the first time.

Players must get at least five per cent of the vote each year to remain on the ballot for the following election. 

Other holdovers from previous ballots back this year include Scott Rolen (52.9 per cent last year), Omar Vizquel (49.1), Billy Wagner (46.4), Todd Helton (44.9) and Gary Sheffield (40.6).
