Kyle Collinsworth tore his ACL in BYU's WCC Tournament Championship Game loss to Gonzaga on Tuesday.

Collinsworth will undergo surgery early next week.

Collinsworth was named to the All-WCC First Team and the WCC All-Tournament Team this season. He led the Cougars in rebounding (8.1 rebounds per game) and assists (4.6 assists per game) and was second on the team in scoring (14.0 points per game) and steals (1.7 steals per game).

Joel Embiid is out indefinitely after being seen in Los Angeles by a spinal specialist, but he will not require surgery.

The doctor confirmed the diagnosis of a stress fracture.

Embiid will miss the Big 12 Tournament and likely the first two rounds of the NCAA Tournament. Bill Self is hopeful that Embiid could return for the later rounds.

Embiid had become the player most general managers would select with the first overall pick in the 2014 NBA Draft, ahead of Andrew Wiggins and Jabari Parker.

"Now it's a three-man race again -- and Embiid might be No. 3 depending on how his back checks out by doctors," said one GM to Jeff Goodman of ESPN.

Joel Embiid will fly to California on Monday morning to see a back specialist.

Embiid has been out since last week's loss to Oklahoma State.

‘We wanted to get a second opinion and wanted to send him to the very best authority,” Self said following the game according to Gary Bedore of KUSports.com.

“Hopefully we get real positive news. Hopefully he can be on the practice floor very very soon. We will not put him out there just because he feels better but because the doctors says it’s time to get back out there. Hopefully it will be real soon, if not we’ll sit him a little longer. We still don’t think it will affect (his participation in) the NCAA tournament in any way.”

Joel Embiid will miss the final two regular season games for Kansas with a lower back strain.

Embiid could also miss part or all of the Big 12 conference tournament.

"There is no reason why he should not be feeling much better by the NCAA tournament," Bill Self said. "The doctors feel that amount of time off should do him wonders for how he is feeling."

Embiid miss the Jayhawks' game against TCU on Feb. 15 with the same back injury, but came back to average 14 points and 10.3 rebounds the past four games.
