Matt Forte left Soldier Field on Sunday in a walking boot after injuring his ankle in the Chicago Bears' 28-10 win over the Vikings.

Forte suffered a sprained ankle in Week 2 and missed one game.

Michael Bush will receive a bulk of the carries in Forte's absence.

"I've been in the league long enough that when that happens, I'm always ready,'' Bush said.

Bush has 60 yards and two touchdowns on Sunday.
