Stafford leaves with knee injury

Posted by ESPN.com’s Kevin Seifert

CHICAGO -- A right knee injury appears to have ended the day of Detroit quarterback Matthew Stafford. Daunte Culpepper has replaced Stafford at Soldier Field with 6 minutes, 41 seconds remaining in the game.

Stafford suffered the injury during a third-down sack by Bears defensive end Adewale Ogunleye. Stafford immediately grabbed the knee, got up slowly and limped to the sideline. Stafford is standing on the Lions’ sideline in no obvious pain, and if he’s seriously injured, no one is acting that way.

Still, with the Bears’ pass rush having a good day -- and a 41-24 deficit -- there’s probably no reason to send Stafford back out.
