Wells hurt his toe early, but by and large hadn't been effective against the Philadelphia Eagles, recording only 18 yards on eight carries. Meanwhile, his substitute, Ryan Williams, came in and averaged 6.4 yards per carry, putting up 83 yards on 13 carries. It's not clear how severe Wells' injury is, but he claimed to have sat out three weeks with a similar toe injury at Ohio State.
The St. Louis Rams were more or less injury free in their loss to the Chicago Bears: Kendall Langford left the game at one point, but he's okay, while Steven Jackson showed no effects of a groin injury.
