BOSTON (CBS) — Patriots training camp kicks off on Thursday, but players dealing with injuries and health issues reported to Foxboro on Sunday. Six of those players will open camp on active PUP, including running back Sony Michel.

Players can come off of active PUP at any point during training camp and the preseason, but those who remain on PUP at the start of the regular season would have to sit out the first six weeks.
