Reliable Chicago Tribune Bears writer Vaughn McClure is hearing from a source that the Bears are placing wide receiver Johnny Knox on the active PUP (physically unable to perform) list to start training camp:

This move was expected as Knox recovers from back surgery for the fractured vertebrae he suffered in December against the Seahawks.

Under the active PUP list, Knox can be activated at any point before the regular season begins. He's allowed to still be in team meetings, rehab, run, lift weights, etc., but can't participate in team practices.

If he begins the regular season on the PUP list, he couldn't be activated until a window between weeks 6-9 of the season.

Knox told the Tribune's Brad Biggs, "There’s really no timetable. We’re all taking our time. They’re not rushing me, I’m not rushing myself. This was a serious injury. Right now I’m setting small goals, taking a little bit at a time. At first I knew it was going to be hard to run. But now I’m running better than I thought I would. I’m getting my weight back a little, doing heavier weights. So doing good."

UPDATE: The Bears have officially placed Knox on the active PUP list (Source: Zach Zaidman).
