Arkansas put football coach Bobby Petrino on paid leave Thursday after he failed to disclose he had been riding with a female employee half his age when his motorcycle skidded off the road over the weekend. Petrino apologized and said he had been concerned about protecting his family and keeping an "inappropriate relationship from becoming public." "I will fully cooperate with the university throughout this process and my hope is to repair my relationships with my family, my athletic director, the Razorback Nation and remain the head coach of the Razorbacks," he said in a statement issued by the university.
