Charles Tillman has a chipped bone in his foot, a league source told Chicago Tribune reporter Vaughn McClure.
The Chicago Bears cornerback had his foot stepped on by Minnesota Vikings tight end Rhett Ellison in the second quarter of his team's 28-10 victory over the Vikings on Sunday. He left the game, came back and left again.
The injury might not be as bad as it sounds, and the man nicknamed Peanut could play through it. He left Soldier Field with a walking boot on his right foot. Sunday was a rough one for the Bears injury-wise. Starting guard Lance Louis was lost for the season. Running back Matt Forte is battle an ankle injury.
Kelvin Hayden would move up the depth chart if Tillman can't play Sunday against the Seattle Seahawks.
The Bears and San Francisco 49ers are generally considered the top two defenses in the NFL. Tillman is a huge part of that in Chicago and would be missed.
