BOSTON (CBS) — Training camp gets underway on Thursday for the New England Patriots, but a handful of players will not be taking the field when it begins.

Cornerback Alfonzo Dennard (shoulder), wide receivers Aaron Dobson (shoulder) and Jeremy Gallon, defensive tackle Tommy Kelly (ACL) and special teams captain Matthew Slater will all open training camp on the active/physically-unable-to-perform list (or the PUP list), according to’s Field Yates.

Dobson, who the Patriots drafted in the second-round in last year’s draft, underwent surgery in March to repair a stress fracture in his left foot. He did not take part in organized team activities or minicamp this off-season.

Being placed on the PUP list means those players have not been cleared by the team’s medical staff. Players are eligible to come off the active/PUP list at any time.

Yates also reported Monday that first-round pick Dominique Easley, running back Roy Finch, linebacker Deontae Skinner and offensive tackle Chris Martin will open camp on the active/non-football injury list.

Much like players on the PUP list, players on the active/non-football injury list can be activated at any time.

Two notable omissions from either list are tight end Rob Gronkowski and nose tackle Vince Wilfork, who both suffered season-ending injuries last season.
