Noticeably absent from the list is Dee Milliner, who is working back from an Achilles tendon injury.
Ridley's status on the PUP is no surprise as he is coming off an ACL tear in his 2014 season with the Patriots. For now the job seems to be Chris Ivory's, but we will have to see how training camp plays out and how soon Ridley can hit the field. My thought is that it is not unforeseeable for Ridley to start the season on the PUP.
As far as Colon, starting training camp on the PUP isn't a great way to begin, but we foresee him having to fight for a roster spot on this team if he can't prove that he is the team's best outright starter at guard. We shall see how quickly Colon can move from the PUP to the active roster, but the longer he stays there the tougher his chances might get.
