Players who enter the season PUP can not come back "anytime". They have to wait until after our 6th game is played before returning to practice.
All that being said its def. possible that we do in fact keep 7 as insurance, especially since outside of Smith and Lafell none of our other receivers have shown the ability to stay healthy and participate in all 16 games.
I could see us putting kugbilla on pup and keeping 7 WR's until week sixish.
