Rookie coach Mike Pettine tried to teach rookie cornerback Justin Gilbert and rookie running back Terrance West a lesson Sunday by reducing their playing time.

Gilbert, the No. 8 pick, didn’t play until the second quarter of Cleveland’s 17-13 loss to Carolina. West was active, but didn’t play at all.

“Neither of those guys had a very good week for us and that’s why you saw the lack of repetitions for them.”

Consistent effort and solid practice weeks have been problems off and on for Gilbert and West. Gilbert fell behind less heralded rookies on the depth chart, and West was a healthy scratch in Week 6.

With No. 1 corner Joe Haden inactive with a shoulder injury, Gilbert would be the natural to replace him. Instead, fourth-round rookie Pierre Desir got the call and played every snap.

Gilbert only played in the nickel package, and not until undrafted rookie Robert Nelson and safety Jordan Poyer had taken their turns. Normal nickelback K’Waun Williams, an undrafted rookie, missed his second straight game with a hamstring injury.
