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." Knox was second in the NFL with 19.6 yards per catch last season, when he led the Bears with 727 receiving yards. The fourth-year player also led the team with 960 receiving yards in 2010. He was added to the Pro Bowl as a kick returner after the '09 season as an injury replacement.
