Was more referring to being activated from the PUP list. He's not allowed to practice with the team while still on it.
But I do agree, he will likely just be getting back into things (assuming he's brought back this week) and they have no need to rush him back against Pitt. KC would be a tough one without him but having the bye after, it does make more sense to just let him get the reps in so he's ready for GB.
