Didn't see this posted, apparently an opening developed with Warner's groin injury: http://msnbc.msn.com/id/9508887/
If he cannot be out McCown he may never get a chance to play. McCown is one of the worst QB's i have ever had the displeasure of watching. Of course he is way behind on learing this offense, and supposedly John Navarre is 3rd string, so I do not know how likely it is that he will play.
