The Patriots will begin training camp on Thursday, but there will be a handful of players who won't be participating right away.
The Patriots placed Logan Mankins, Brandon Spikes, Sebastian Vollmer, Daniel Fells, Myron Pryor, and Jake Ballard on activePUP list on Monday, according to ESPNBoston.com.
Mankins is recovering from ACL surgery after injuring it in Super Bowl XLVI and it's unclear when he will be back at this point. Brandon Spikes (knee) and Sebastian Vollmer (back) are also recovering from offseason surgery.
Jake Ballard (knee) is expected to miss the 2012 season.
A noticeable name not on that list is tight end Rob Gronkowski, who has had quite the summer for himself and appears to be ready for what training camp has in store.
Another good sign is the absence of defensive end Jonathan Fanene, who injured his left leg during Patriots minicamp last month.
There was some hope that tight end Daniel Fells (leg) would be ready for the start of training camp, but that doesn't look to be the case. The Patriots reportedly worked out Visanthe Shiancoe earlier this week and will continue to look at tight ends as long as Fells is down.
The Pats have until the end of the preseason to take these players off the list. Any player on the list after that will be forced to miss the first six weeks of the regular season.
