Memphis big man Chad Rykhoek, a graduate transfer who made his NCAA debut earlier this season after an injury-plagued stint at Baylor, was taken off the court on a stretcher with what appeared to be a serious left ankle or leg injury in the first half Saturday against Oklahoma.
Rykhoek injured his left leg with 5:14 remaining in the first half after a collision with Oklahoma forward Matt Freeman under the basket after a missed shot.
Memphis coach Tubby Smith said after the game that Rykhoek suffered a dislocation and that his recovery timetable is uncertain.
The game was delayed for about five minutes after the injury. His leg was immobilized before he was moved, though Rykhoek didn't appear to be in too much pain.
His parents were summoned to the court and members of both teams surrounded him while the Sooners crowd gave him a standing ovation.
Rykhoek transferred to Memphis earlier this year after a string of injuries forced him to leave Baylor, where he never played a minute of basketball. The Fort Worth, Texas, native was rated as a top-150 recruit by Rivals when he enrolled at Baylor in 2012.
The 6-foot-11 Rykhoek started all 11 of Memphis' games this season and was averaging 6.4 points and 2.8 rebounds per game entering Saturday.
Information from The Associated Press was used in this report.
An earlier version of this story incorrectly reported that Rykhoek was playing in his first career college game Saturday. Rykhoek had not played prior to this season, but started all 11 of Memphis' games this season.
