Chicago Bears WR Johnny Knox acknowledged on Wednesday that he could miss the entire 2012 season after undergoing back surgery to stabilize a vertebra following a December injury.
"It could happen, but I’m staying optimistic," said Knox, according to Mark Potash of the Chicago Sun-Times. "My main focus is in the weight room. I’m not in a rush. This is my spine, the core of my body I’m dealing with. It’s not my knee, ankle or shoulder. I’m taking my time."
