San Antonio star Victor Wembanyama’s season is likely over after he was diagnosed with a blood clot in his right shoulder, a condition that will sideline one of the league’s brightest stars and is the second massive health-related hit for the Spurs in a matter of months.

Wembanyama is beginning treatment immediately and the Spurs are working under the expectation that the 7-foot-3 center from France will fully recover, said a person with knowledge of the situation who spoke to The Associated Press on condition of anonymity because those details were not released publicly.

It may even be possible for Wembanyama — the NBA’s leading shot-blocker this season and a first-time All-Star — to play this summer for France in the European championships if he chooses, the person said.

“You can’t replace Vic,” said Spurs guard Chris Paul, whose team beat the Phoenix Suns 120-109 Thursday. “I can’t stand on a guy’s shoulders and block every shot that comes to the rim. Aside from his basketball ability, his charisma and what he brings into the locker room, I think, is what we’ll miss the most.”

Wembanyama’s condition — deep vein thrombosis — was diagnosed this week after he returned from the All-Star Game, the Spurs said Thursday. It is almost always treated with blood-thinning medication, and players in contact sports such as basketball have long been advised to avoid playing while using such medication because of the heightened chance of bleeding.

Wembanyama’s diagnosis comes about 3 1/2 months after Spurs coach Gregg Popovich had a stroke and was forced to take a leave from the sideline, with assistant coach Mitch Johnson serving as acting coach ever since.

Wembanyama, 21, is averaging 24.3 points, 11 rebounds, 3.8 blocks and 3.7 assists; the only other player to finish a season averaging all that was Kareem Abdul-Jabbar in 1975-76.

MAVS’ DAVIS OUT AT LEAST TWO MORE WEEKS: Anthony Davis will be sidelined at least two more weeks with the groin injury sustained in his Dallas debut, while the Mavericks said Thursday their star forward is making good progress in his recovery.

Davis was dominant in the first half of his only game with the Mavericks against Houston on Feb. 8, but pulled up lame late in the third quarter of Dallas’ 116-105 victory.

The 10-time All-Star had missed his last two games with the Lakers because of an abdominal injury before the seismic trade that sent fellow superstar Luka Doncic to Los Angeles.

BUCKS’ PORTIS SUSPENDED 25 GAMES: The NBA has suspended Milwaukee forward Bobby Portis Jr. for 25 games without pay because he tested positive for the painkiller Tramadol, a violation of the league’s anti-drug program.

Portis cannot play again until April 8 — the 79th game of Milwaukee’s 82-game regular-season schedule — at the earliest. His suspension started with the Bucks’ game Thursday against the Clippers.

Portis took the painkiller “unintentionally,” said his agent, Mark Bartelstein. Portis thought he was taking Toradol, which is approved and is something that he has taken before, Bartelstein said in details first given to ESPN and that he later confirmed to The Associated Press.

Portis, 30, will lose $2,858,701 in salary because of the suspension.
