Philadelphia 76ers center Joel Embiid has been diagnosed with a displaced flap of the meniscus in his left knee and could undergo surgery, The Athletic reported on Saturday.

Another option for the reigning NBA MVP would be to rest and rehab the injury instead of having a procedure on the knee.

Embiid was injured in the 76ers' loss to the Golden State Warriors on Tuesday in his first game back after missing two contests due to an issue with his left knee.

Embiid is the NBA’s leading scorer with 35.3 points per game and is averaging 11.3 rebounds and 5.7 assists in 34 appearances.

He had a franchise-record 70 points to go along with 18 rebounds on Jan. 22 against the San Antonio Spurs.

Scotland ended 22 years of hurt in Cardiff after they thwarted a spectacular Wales fightback to win an extraordinary Guinness Six Nations clash 27-26.

It was Scotland’s first win in the Welsh capital since 2002 – ending a run of 11 successive defeats – to set up a mouth-watering Murrayfield encounter against France next Saturday.

But Wales made them fight every inch of the way after the Scots had breezed into a 27-point lead after 42 minutes, with wing Duhan van der Merwe scoring two tries including a virtuoso long-range effort while prop Pierre Schoeman also touched down.

Captain Finn Russell kicked three conversions and two penalties, but it only told half the story.

Flanker James Botham’s try sparked the Welsh recovery then he was followed over the line by Rio Dyer, Aaron Wainwright and debutant Alex Mann, with Ioan Lloyd kicking three conversions.

Scotland found themselves on the rack after hooker George Turner and centre Sione Tuipulotu were sin-binned during the second period, yet they successfully closed the game out and left Wales wondering what might have been.

Both teams started brightly under the stadium’s closed roof and Scotland struck first when Russell kicked an angled 20-metre penalty, before quick lineout ball gave Tuipulotu a chance that Wales managed to defend.

Wales, though, could not stop wave after wave of attacks that led to the game’s opening try after 11 minutes.

Russell created initial space and after a strong run by wing Kyle Steyn, Scotland’s forwards took over and Schoeman crossed from close range. Russell’s conversion made it 10-0.

Scotland enjoyed scrum and lineout dominance and they controlled the opening quarter, even if Wales established promising attacking positions at times.

Russell extended Scotland’s lead with a second penalty – Wales wing Josh Adams was punished for throwing the ball away and denying Scotland a quick lineout throw – and alarm bells were beginning to ring for Gatland’s team.

Inevitably, Russell was at the heart of everything good about Scotland’s magic and he weaved his magic to devastating effect 10 minutes before half-time.

Scotland set up a strong position inside Wales’ 22 and the rest was all about Russell, who ghosted into space, threw a half-dummy pass, then delivered a try on a plate for Van der Merwe.

There appeared no way back for Wales, with their problems showing no sign of abating as fly-half Sam Costelow went off for a head injury assessment as Scotland led 20-0 at the interval.

It got even worse for Wales just two minutes into the second period when Van der Merwe carved them open from deep to claim a blistering solo touchdown, and Russell’s conversion put further daylight between the teams.

Costelow failed his HIA and Gatland made three half-time changes, sending on scrum-half Tomos Williams, hooker Elliot Dee and prop Keiron Assiratti, and Wales opened their account when Botham crashed over.

Turner was sin-binned for an offence in the build-up to Botham’s try and Wales struck again, this time through Dyer, with Lloyd’s conversion cutting the gap suddenly and unexpectedly to 15 points.

It was panic stations for Scotland when Tuipulotu went into the sin bin and Wales punished them immediately as Wainwright touched down for a third try in 13 minutes, with Lloyd converting.

The capacity crowd could scarcely believe what they were witnessing, but it was Williams’s influence off the bench that proved key as he injected pace and purpose into Wales’ game.

And when Mann claimed a 68th-minute try, again converted by Lloyd, the improbable dream edged closer, with Scotland looking bewildered and devoid of answers.

But they somehow held out, Wales left with the consolation of two losing bonus points.

Jamie George is convinced England can win the Guinness Six Nations but accepts they must learn fast after edging Italy 27-24 in Rome.

England were outscored 3-2 on the try count and were outplayed in the first half, which they finished 17-14 behind, but they rallied with an important Alex Mitchell try and two penalties from George Ford.

It was the closest Italy had come to beating them in 31 Tests between the rivals and even allowing for the five new caps in Red Rose ranks, it was a shaky start to post-World Cup rebuilding.

While England were labouring to victory at the Stadio Olimpico, Ireland looked sensational in a crushing win over France in Marseille the previous evening.

When asked is there is enough quality in the team to challenge Ireland, George said: “Absolutely. I don’t want anyone to be involved in this squad if they don’t genuinely believe we can go and challenge the best and win this tournament.

“Looking at Ireland, they were very impressive. Not many teams go to France and perform like that. It’s a blueprint for us, and any team, to look at how they approached that game.

“For us, we’re going to be learning fast and we need to make sure we learn our lessons, being very clear about what we want to go after this game.

“We’ve got a great opportunity to be back in front of our fans against Wales next weekend and really give them something to smile about.”

England have a new defence coach in Felix Jones and at times they were exposed by an inspired Italy, who took advantage of the lack of familiarity with the new system to engineer three tries.

“I’m very pleased the players found a way to change and win the game,” head coach Steve Borthwick said.

“There were areas we improved upon and it was brilliant to see five players making their debuts in the Six Nations, which doesn’t happen very often.

“But having said that there were plenty of areas we need to be better. Italy scored too easily and we need to look very closely at things that need to be improved around our defence.

Italy head coach Gonzalo Quesada took little comfort from knowing that it was the closest the Azzurri had come to beating England in 31 attempts.

“When I spoke to the players and coaches in the changing room, no one was happy with this narrow defeat,” Quesada said.

“That’s something that’s very important for me because I didn’t care to look at the closest gap in history.

“I’m proud of the spirit showed by the team. England were close to our tryline many times but we kept them out, which is the team we want to be.”

Emmet Mullins appears to have another potential star on his hands given the way Jeroboam Machin cruised to victory in the Donohue Marquees Future Stars I.N.H. Flat Race at Leopardstown.

Continuing the dominance of the Mullins family on the opening day, Mullins’ uncle Willie was responsible for four winners, while cousin Danny rode three of them. This time is was Grand National winner Emmet taking the limelight.

The race saw the reappearance of last year’s winner, A Dream To Share, who went on to follow up at Cheltenham and Punchestown. But despite being sent off the 8-11 favourite, a repeat victory never looked likely.

Jeroboam Machin (12-1) was ridden by Derek O’Connor, who sported the light blue colours of Paul Byrne, owner in their early days of the likes of National hero Noble Yeats and The Shunter.

Having travelled sweetly to the lead, he had no problem in pulling four and a quarter lengths clear of You Oughta Know.

So impressive was the win that a number of firms promoted him to favouritism for the championship event at Cheltenham.

Mullins said: “Watching him work the last few weeks wouldn’t inspire confidence and I think I said the same after his debut, he doesn’t show much at home.

“But any time we take him away he lights up and I don’t mind what he does at home if he saves his best for the track.

“He’s green but I don’t know if that will come out of him, he comes up the gallop at home as quick with a 90-rated horse as he does a 140-horse, that’s just him. I’m just glad he’s got that bit of class.

“There’s plenty of horses we have that fall by the wayside, but Paul’s very good, he gives me free rein. I picked this lad out of an auction point-to-point which may not have been that sexy, but I loved the way he winged the last that day.”

When asked if he could go to Cheltenham, he said: “Well we came in the right-hand side of the parade ring instead of the left today, so we could go either way!”

Madara, one of only three runners from the UK declared at the Dublin Racing Festival, ran out a ready winner of the Ryanair Handicap Chase.

Claimed by Sophie and Christian Leech out of an Auteuil chase in October, his three previous runs for the yard had all been at Cheltenham, winning on the most recent of them.

No stranger to running their horses in France, they snapped up James Reveley to ride, a former champion jockey over there.

British and Irish race fans had a recent reminder of the Yorkshireman’s qualities on Boxing Day when Il Est Francais led his rivals a merry dance at Kempton.

Reveley bided his time on this occasion, making sure not to hit the front too soon on the seven-year-old – but approaching the final fence, he could wait no longer.

Once over that obstacle, he put the race to bed, stretching clear to win by two and three-quarter lengths as the 4-1 joint-favourite.

Sophie Leech said: “He’s a fantastic horse and I’m so happy. My son Ed and my husband Christian do all the race planning and this fitted timing-wise.

“We are used to travelling, as we have more runners in France than we do in England. It looked like a really nice opportunity and Bryan (Drew, owner) and all the lads involved were really keen to come over and have a go.

“We’re a very small yard and the team at home work tirelessly, so thank you to them. We’re delighted.

“We’re staying for the racing tomorrow, so it’ll be a good old night tonight!

“We’ve had runners at Punchestown before and love coming over here.”

When asked if Madara could now head for the Grand Annual, she added: “We were thinking of the Plate for him (at Cheltenham), because we thought he’d like a step up in trip.

“He was beat over the Old course and I think the New course suits him better. I don’t know now because he looked to have plenty of pace there. It’s a nice problem to have.”

Reveley commented: “I’m over the moon, it’s my first winner in Ireland. To be fair, it was a good bit of placing by Sophie and Christian.

“I watched his Cheltenham race over and over and thought yeah, Leopardstown will suit him down to the ground – big fences, stiff track and a bit of soft ground, it was ideal for him.”

Maxxum produced a fine weight-carrying performance to give young jockey Carl Millar by far the biggest success of his fledgling career in the Race And Stay At Leopardstown Handicap Hurdle.

Millar only had eight previous winners to his name but proved great value for his 7lb claim on Gordon Elliott’s top weight.

Maxxum had won at Leopardstown last Christmas and went off 7-4 favourite for this very race 12 months ago, only to disappoint.

Having looked in the grip of the handicapper, Elliott sent him chasing.

He had been back over hurdles for his last two outings but was sent off at 28-1, having been pulled up on the most recent of those.

Millar was positive from the outset, though, and while Gaoth Chuil travelled much better, Maxxum stuck to his task to win by three-quarters of a length.

“Carl is a good lad. He’s well able to ride and just needs to tidy himself up a little bit now, get on the simulator. He’s a good lad and works hard,” said Elliott.

“Maxxum is a bit hot and cold and I thought the ground might have gone a bit soft for him. When you are in these handicaps, you never know.

“We said we’d keep it simple, pop him out handy and see what happens.”

Nickle Back galloped to a memorable Grade One victory in the Virgin Bet Scilly Isles Novices’ Chase at Sandown following a bold front-running ride from James Best.

It was a fairytale first success at elite level for the jockey and West Wratting trainer Sarah Humphrey, although the race was marred by a fatal fall for Hermes Allen at the second-last.

Best and 10-1 shot Nickle Back established a healthy lead in the early stages, with 8-13 favourite Hermes Allen heading the chasing pack.

Some exuberant leaps allowed the pacesetter to extend his advantage to fully 20 lengths with three to jump and he was again foot-perfect at the Pond Fence.

After Nickle Back bounded clear from two out, Djelo clawed back some of his lead up the stiff home stretch but Best’s mount was not for catching, prevailing by seven lengths,

“I just cannot believe it,” Best told ITV Racing. “As a small child growing up, you watch these races on the television on a Saturday and you dream of becoming a jockey and winning races like this.

“A massive thank you to Sarah and all the team, I’m just gobsmacked, as I was when winning on him in his first chase at Warwick.

“For them to put their faith in me on this wonderful horse, it means so much and I just can’t believe it.

“He was a bit brave early on and that kind of twisted my arm second time down the back – for goodness sake, just go with him!

“He loves galloping and he loves jumping, so just get a breather when I could.

“Congratulations to Sarah, as she has done a wonderful job with this horse, who is quite fragile and not easy to train.”

Nickle Back was cut from 50-1 to 20-1 for the Turners Novices’ Chase at Cheltenham by Betfair, with Defi Du Seuil having done the same double five years ago.

Humphrey said: “I’m elated and it hasn’t really hit me yet, because to be perfectly honest, we never thought we would win.

“We thought we would put up a good show and give them a good run for their money, but to win is what dreams are made of. There will be a big party when it all sinks in.”

She added: “James does a very good job and if you just leave him alone, he knows what he’s doing. If you interfere, you are in trouble.

“James did a brilliant job today, he knows him well now and he trusts him and that’s just what you’ve got to let him do – get into that rhythm.

“He’s very slick from the front to the back of the fence, so let him pop away and trust him.

“He’s quite quirky, but in a very nice way – he’ll jump out of his field on a regular basis. You just have to keep a lid on him really and keep everything nice and calm.

“Like all good horses, they all have their quirks don’t they, but we’ve found a way to manage him.”

England survived a scare at the Stadio Olimpico to launch their post-World Cup rebuild with a 27-24 victory over Italy in their Guinness Six Nations opener.

For only the third time in the history of a rivalry spanning 31 Tests, inspired Italy led at the interval, but their 17-13 advantage was methodically picked apart by Steve Borthwick’s men.

Tommy Freeman proved England’s most effective weapon in attack, the Northampton wing roaming the pitch in search of impactful moments, but it was Elliot Daly and Alex Mitchell who finished the tries.

As promised by new captain Jamie George, the favourites played with greater freedom and there was less kicking than in the first year of Borthwick’s reign, at least until the focus switched to grinding Italy down in the final half-hour.

But overall the more exciting rugby was played by the Azzurri, who showed ingenuity and ambition in their pursuit of a maiden victory against their rivals and their second try scored by Tommaso Allan was a beauty.

New caps Ethan Roots, Fraser Dingwall, Fin Smith, Chandler Cunningham-South and Immanuel Feyi-Waboso brought a freshness to England, who ended their four-year stretch of beginning the Six Nations with a defeat, but the initial outlook was far less rosy.

They lost replacement prop Ellis Genge to a foot injury shortly before kick-off and that was only the start of their problems as early enterprise from Italy engineered a try for Alessandro Garbisi.

It rewarded their brighter start and came when Lorenzo Cannone was sent through a gap, with Garbisi able to scoop up the offload.

With Allan and George Ford exchanging penalties the score read 10-3, but the deficit provided the jolt England needed as Freeman glided into space and delivered the scoring pass to Daly.

The try had been coming but it was quickly overshadowed by a stunning riposte from Italy, whose precise passing and clever running off set-piece ball was executed beautifully for Allan to score.

Two penalties by Ford kept England snapping at the Azzurri’s heels at half-time and they needed to regroup quickly, particularly in defence, to spare themselves an unwanted slice of history.

Reassurance came when Mitchell jinked and spun his way over the whitewash in the 45th minute and for the first time the visitors led.

Italy’s play now lacked its earlier precision and they were pinned deep in their own half as England tightened the screw with Ford landing successive penalties to propel them 10 points ahead.

Handling errors cost the Azzurri time and again and their line-out continued to malfunction in an exasperating period for the hosts that also saw Allan miss an important penalty.

Daly was sent to the sin-bin for a trip as Italy hunted the try that would haul them back into contention, but they were unable to produce any more magic as the upset slipped from their fingertips despite a last-gasp Monty Ioane touch down.

Galopin Des Champs is odds on for the Cheltenham Gold Cup after registering back-to-back success in the Paddy Power Irish Gold Cup at Leopardstown.

Leading from flag-fall, Paul Townend was content to set a sedate pace on Willie Mullins’ 1-3 favourite, with his old rival Fastorslow never letting him get too far in front.

The pair had met three times in the past, with the score heading into this contest in favour of Martin Brassil’s chaser by two victories to one.

Team Closutton were determined to level the scores before heading to Cheltenham and Townend – who had picked the wrong Mullins-trained representative in the first three Grade Ones of the afternoon – was always in control.

J J Slevin attempted to make his move after the second-last and aimed to get the rail, but Townend was alive to it and made sure it was not straightforward, while Conflated was not completely out of it on the far side.

Galopin Des Champs jinked to his left approaching the last which just put Fastorslow off for a stride or two, while Conflated unseated Jack Kennedy, but just like at Christmas the winner’s most impressive part was the final 100 yards and he pulled four and a half lengths clear.

The winner is now 4-6 (from evens) to repeat his Cheltenham success in March with Betfair and Coral.

Maxxum produced a fine weight-carrying performance to give young jockey Carl Millar by far the biggest success of his fledgling career in the Race And Stay At Leopardstown Handicap Hurdle.

Oleksandr Usyk could still fight in Saudi Arabia on February 17 despite his showdown with Tyson Fury being shelved, his promoter has confirmed.

This month’s proposed undisputed world heavyweight fight between Usyk and Fury in Riyadh was postponed on Friday after the British boxer suffered a “freak cut” above his right eye in sparring.

It was the latest twist in a long-awaited saga to have all the belts on the line in boxing’s blue-ribbon division, but Usyk could still ensure the card goes ahead.

Usyk’s promoter Alex Krassyuk confirmed on Saturday morning during an Instagram live that he is working on finding the Ukrainian a new opponent, with Filip Hrgovic being lined up due to the Croatian boxer being the mandatory challenger for Usyk’s IBF belt.

“Will Usyk be fighting on the 17th? We are working on that and in the next couple of days a final decision will be taken,” Krassyuk said.

“There is only one option because the IBF has sanctioned the undisputed fight on the condition that after this fight the champion has to fight the mandatory, which is Hrgovic. That means if the champion fights someone else, he will be stripped of his belt by the IBF.

“With Hrgovic, there is a slight chance.”

Fury apologised on Friday night after confirmation that his highly anticipated bout for all four major world heavyweight titles with Usyk had to be postponed.

The facial cut suffered by the ‘Gypsy King’ required medical attention and “significant stitching”, which rules out the possibility of a new date being quickly found.

Krassyuk added: “If we speak about undisputed, it is still a question whether it will happen some day at all?

“We have tried so many times to make it and the more people doubt it will ever take place.

“Let’s hope, let’s pray. Of course we wish Tyson a soonest recovery and hopefully next time nothing will stop him taking punishment from Usyk.”

It Etait Temps completed a dream hour for Danny Mullins when winning the Goffs Irish Arkle at Leopardstown, where Marine Nationale was a huge disappointment back in fifth place.

Having already won the opening two Grade Ones on Dancing City and Kargese, Mullins was riding full of confidence, but faced huge opposition in the shape of Barry Connell’s unbeaten Marine Nationale – not to mention Facile Vega, a stablemate of the Willie Mullins-trained winner.

It was Gordon Elliott’s Found A Fifty who ensured there was to be no hanging about and with Facile Vega on his heels, there was no letting up in the pace.

Sent off the 4-7 favourite, Marine Nationale had been settled in third, but his jumping was not as assured as on his debut and Il Etait Temps moved passed him down the back straight.

As the field turned in Marine Nationale briefly threatened to take a hand, but a bad mistake at the last sealed his fate.

Found A Fifty looked like he had done enough to hold on, but Il Etait Temps gamely dug in to win by a neck at 6-1.

The winner is now 5-1 from 14s for the Arkle at Cheltenham.
