BEREA, Ohio -- The Cleveland Browns may have cornerback issues when they play the Oakland Raiders on Sunday. Justin Gilbert appeared on the injury report Thursday with a hamstring injury, and on Friday, nickelback K'Waun Williams was ruled out with a concussion.

That could leave the Browns with three healthy corners -- Joe Haden, Tramon Williams and Pierre Desir -- against an offense that ranks ninth in the league in passing (267 yards per game).

In Sunday's win over the Baltimore Ravens, Raiders quarterback Derek Carr threw for 351 yards and three touchdowns, and Amari Cooper and Michael Crabtree became the first pair of Raiders in 10 years to each have more than 100 yards and a touchdown.

Coach Mike Pettine said Desir would be the third cornerback and safety Johnson Bademosi would move to corner. Bademosi struggled at the position in training camp and the preseason. It's possible the Browns could move safety Jordan Poyer to the corner spot as well.

Gilbert being available to play is key to rounding out the group. He missed the first two games of the season with a hip issue but practiced Monday and Wednesday. The hamstring injury showed up on Thursday, and he was listed as limited on Friday's injury report.

"We'll get another evaluation tomorrow and see where we are," Pettine said.

The Browns have been very high on K'Waun Williams since they signed him as an undrafted free agent last season, but this is the third concussion he has had that has forced him to miss time.

"He complained of headaches [Thursday], and we had him evaluated," Pettine said. "They went ahead and chose to be cautious and put him in the protocol."
