Minnesota Vikings quarterback Christian Ponder left the team's game with the Chicago Bears with a concussion just before halftime, and his status for next week is up in the air.
Ponder took a helmet-to-helmet hit on a two-yard completion to Greg Jennings near the end of the first half, and went to the locker room without his helmet to be evaluated.
After Ponder left the game, Matt Cassel led a 10-point comeback in the fourth quarter and eventually directed the Vikings to a 23-20 overtime win. Cassel threw for 243 yards in relief of Ponder. Josh Freeman would be the backup to Cassel if Ponder misses time. But it's a tough matchup at Baltimore in Week 14.
