BEREA, Ohio -- The Cleveland Browns likely will have defensive lineman Ahtyba Rubin on the field when they play the Oakland Raiders on Sunday.

“He’s had a good week,” said coach Mike Pettine. “He feels good. He’s been cleared. Obviously feel real good about him.”

Rubin missed the last two games with an ankle injury, but though Rubin is a confident guy, don’t expect the return of one player to be a panacea for the Browns' ailing run defense. In the four games Rubin played, the Browns gave up 152.5 yards rushing. For the season, they are giving up 155.5 yards. Improvement has to come from more than just one guy.

Pettine also said he had decided who would start at center and right guard, but declined to name them, citing a strategic advantage in withholding the information until Sunday.

John Greco, who started at center following the injury to Alex Mack, said he got reps at center and right guard, but didn't know how the Browns would line up. The team has until Saturday at 4 p.m. if it wants to activate Nick McDonald off the non-football injury list.

Backup safety and designated punt-catcher Jim Leonhard missed Friday’s practice after hurting his ankle in practice on Thursday. Pettine said he expected Leonhard would play.

There’s a chance Billy Winn could return from the quad injury that sidelined him for two games. Winn practiced Friday, and if healthy, he could improve the depth on the defensive front.
