Tony Brackens... is he worth a roster spot?

Couldn't he be picked up and put on an 'unable to perform' list. I think it is called PUP?
That way he would not take up an active roster spot until he is healthy and we would not have to cut a D-lineman until he is healthy.

Someone correct me if this is wrong, but I think the PUP list is only for preseason. During the regular season, he would have to take a roster spot unless put on IR where he would be out for the year.

i thought IR was 5 weeks minimum not a year... couldn't find it in ten minutes on nflpa...
but i did find out that 3 weeks on an active roster and you can get our club to repay 15,000$ spent towards college education...
