Oklahoma Sooners senior linebacker Caleb Kelly has suffered a "lower-body" injury that will require surgery and could keep him out months, coach Lincoln Riley announced Thursday.
Riley also revealed that redshirt freshman defensive lineman Jordan Kelley has already undergone surgery for a lower-body injury.
"If there's a silver lining it's the timing of the injuries, with them occurring five months before the season," Riley said in a statement. "I know they'll work their tails off to get back to the field as quickly as possible, and we'll be there with them every step of the way.
