Texas (17-4, 6-2 Big 12) moved into second place in the conference with an 81-69 victory over No. 6 Kansas on Saturday. Felix was in a hard collision with Jayhawks 7-foot center Joel Embiid late in the game.
Felix was knocked to the court, but was able to keep playing and made 7 of 8 free throws over the final 2:36 to help Texas seal its fourth consecutive victory over a ranked opponent.
A statement from a school spokesman announcing Felix's injury did not indicate when he might return.
