I missed this last night, but according to what Stoops said at his post-game press conference, Murray suffered only a knee bruise and was held out as a precaution. The question then comes to my mind as to why he kept everyone else in if he was taking precautions with Murray, but that's why he's making a gajillion dollars and I am typing pointless fan posts on my computer.
Anyways, Murray should be ready to go for the bowl game.
interestingly, the yardage gained from his return gave him the single-season record for all-purpose yards - he is at 2,171 all-purpose yards, eclipsing Quentin Griffin's 2,148 yards that he racked up in 2002.
Aside - Do bowl game stats count in season stats?
