FAYETTEVILLE, Ark. – The following statement is from University of Arkansas football head coach Bobby Petrino regarding quarterback Ryan Mallett:"Ryan Mallett underwent a procedure Wednesday evening to replace a screw in his left foot. We fully anticipated this would need to be done in early to mid-June and the timing of it was intentional to allow him to prepare for the season as much as possible during the summer months. He will be non-weight bearing for the next two weeks and I expect Ryan to return fully after that time period. I am completely confident in our athletic trainers and medical staff and the plan they have put in place for Ryan."
