The big news for the Cleveland Browns right now is the injury to quarterback Colt McCoy, a concussion sustained on Thursday Night Football against the Pittsburgh Steelers. On Thursday, McCoy was sent home before practice, which is not a good sign for his status on Sunday against the Arizona Cardinals. McCoy took a vicious shot to the head by Steelers linebacker James Harrison, and there has been a lot of controversy surrounding the team's decision to send him back into the game after the hit.
If McCoy misses another practice, it's likely that he won't be in action on Sunday. His backup, Seneca Wallace, has been taking all the snaps in practice and would get the start in McCoy's absence. That would make Thad Lewis the No. 2 quarterback. Even if McCoy is cleared to play somehow, it's unlikely that he'd be in action, as he's not yet reached the level where he can really play without preparation and practice snaps.
Harrison was suspended for one game following the helmet-to-helmet hit on McCoy.
