College football’s annual rite of spring seems to be withering.

Texas became the latest major program Thursday to ditch or change it’s annual spring scrimmage that has long been a staple for fans eager to see the rising stars of their program and get a peek into the upcoming season.

Coach Steve Sarkisian announced there would be no Orange & White scrimmage this year, citing the wear and tear of playing 30 games over the last two seasons when Texas twice advanced to the College Football Playoff.

As of Thursday, about half of the 68 Power Four schools had publicly announced dates for spring games. Formats vary, with some schools holding traditional scrimmages and others conducting skills competitions and holding autograph sessions.

Wembanyama expected to miss remainder of season >> 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.

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. The Spurs have said Popovich’s condition is improving, but there is no timetable for his return to the bench.

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 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. Davis then sat the first two games he could have played for Dallas before suiting up against the Rockets.

Milwaukee’s Portis suspended >> 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 starts with the Bucks’ game Thursday against the Los Angeles Clippers.
