I know there hasn't been much reported about Kevin White lately, but after doing some digging, it looks like the team will have to do something with him by November 24th (12 days from now). At that point they will have 3 options:
1. place him on injured reserve (most likely)
2. release him (obviously not going to happen here)
3. bring him back to practice (then have up to 21 days before adding him to 53-man roster)
So if White had a chance to play this year, he could come back as late as December 20th (at Minnesota), 4 months removed from surgery, and would be eligible to play as early as next week if activated (and in game shape, which is not likely). He was only jogging 2 weeks ago, and would have to ramp up to running, cutting, and jumping
Basically, we will know in less than 2 weeks if White will play this year.
My gut says it will ultimately come down to our record after the Broncos game, but I am leaning towards them shutting him down. While the reps are invaluable in a real game environment, I would hate to see him come back too early after all this time off.
