Utah running back Devontae Booker is undergoing minor knee surgery and will miss the rest of the regular season. He could be back for Utah's bowl game though. ESPN700's Sean O'Connell first reported the news here. This is a tough blow for the Utes as Booker is the best offensive football player for the team. Back up running Joe Williams saw his most action of the season last week against Arizona when he filled in for Booker after he missed time in the game because of the knee injury that is now causing him to miss the rest of the regular season.
