Chicago Bears backup running back Michael Bush ended the 2012 season on injured reserve with a rib injury. Bush told the Chicago Tribune he also played most of the season with a fractured bone in his right shoulder.

"How did I play through it?" Bush asked rhetorically after saying he suffered it in a Week 2 loss to the Green Bay Packers. "The same way I was going to play through the rib injury until I realized (the rib injury) was worse than what it was. That's just me. Once I broke my leg (in college) ... if it ain't my leg and it ain't my feet and I can still walk around and run, I'm going to play.''
