Knight's mother posted on Facebook on Sunday a message alluding to the MRI, saying she was hoping everything was fine with Knight's knee. A source later confirmed to Sooners Illustrated Knight had the MRI on Sunday morning.
Knight was uneven in his second career start as OU defeated West Virginia 16-7 on Saturday night. Following a first half where he had his moments, things turned sour for Knight in the third quarter.
He threw two interceptions deep in West Virginia territory and finished the half 1 of 5 for 6 yards with two picks. For the game, Knight was 10-of-20 for 119 yards with a touchdown and two interceptions.
Senior center Gabe Ikard talked about Knight's injury following the game.
"Trevor did some great things and got a little banged up," Ikard said. "We just have to get him healthy and those two guys (Knight and Blake Bell) will continue to battle each other in practice."
Bell replaced Knight at quarterback for OU in the fourth quarter and rushed for 21 yards on two attempts.
OU coach Bob Stoops declined to discuss the quarterback situation following the game, saying it is something he and the coaches will have to discuss this week.
