Crennel said Brady Quinn, who recently suffered a concussion, has been cleared by doctors to practice but not play in a game. That clearance could come later in the week, but Crennel said he couldn’t wait any longer to make his decision.

“I can’t take the chance on practicing a guy and then not have him ready to play on Sunday,’’ Crennel said.

Crennel said he would make a decision on Sunday morning whether Quinn or Ricky Stanzi would be the backup against the Bengals.
