(WSCR) While it is still uncertain whether or not Bears wide receiver Johnny Knox will even play in 2012, he will start the season on the physically-unable-to-perform list.

Knox is working to recover from spinal fusion surgery he underwent in December. Reports indicated the wide receiver was forced to wear a back brace after the surgery and continues to walk with a limp now.

Knox suffered the injury when he was hit awkwardly in the first quarter of a game against the Seahawks.
