NORMAN, Okla. (AP) — Oklahoma receiver Keontez Lewis left Saturday’s game against Kent State in the first quarter after hitting his head on a brick barrier following an attempt at a catch. A pass by Michael Hawkins Jr. was a bit overthrown in the back of the end zone, and Lewis’ momentum took him headfirst into an unpadded section of the wall behind the field. Lewis lay motionless on the grass for several seconds before being attended to. OU Sports Medicine said during the game that Lewis was sent offsite for additional testing, and the outlook for him is “promising.”The brick barrier surrounds nearly all of Owen Field and is relatively close to the action. Lewis has 17 catches for 210 yards and two touchdowns this season.
