LAKE FOREST, Ill. -- Chicago Bears coach Lovie Smith said the decision to sit running back Michael Bush for the final 10 minutes of their 23-6 victory over the St. Louis Rams on Sunday was not injury related, but he acknowledged Bush absorbed a couple of big hits.

Bush started the game in place of the injured Matt Forte, but the Bears opted to play the recently re-signed Kahlil Bell in the final two offensive series while Bush stood on the sidelines holding his helmet.

Bush last carried the ball for a 2-yard gain at the 10:40 mark of the fourth quarter on a first-and-goal play from the Rams' 6-yard line.

"We have a lot of guys that got a little banged up (Sunday) from the physical play of the game," Smith said. "No, we were playing Kahlil Bell before that. Mike took some good shots. You know, he came out one play on a hard hit but it was that type of game.

"It was good to see Kahlil Bell to get some reps. Kahlil can do some of the same things we ask Michael to (do). I still think there is a place for Armando Allen too, which gives you a totally different body type playing."

Bush had 55 yards rushing on 18 attempts. Bell carried the ball 10 times for 20 yards while Allen had just one run for 1 yard.

Smith said on Monday he is "hopeful" Forte can practice this week and be able to play next Monday night at Dallas.
