FOXBOROUGH, Mass. -- After three weeks of shuffling pieces along the offensive line, things are looking up for the New England Patriots.

Rookie right guard Tre' Jackson (left knee) and offensive tackles Sebastian Vollmer (concussion) and Marcus Cannon (toe) all returned to the practice field Wednesday. All three had missed Sunday's win over the Giants.

Jackson injured his knee Oct. 29 against Miami, Vollmer sustained a concussion Nov. 8 against Washington, and Cannon injured his toe Oct. 18 against Indianapolis. This marks the first time all three have practiced since sustaining those injuries.

But the injury news wasn't all good for the Patriots, as starting linebacker Jamie Collins remained out of practice with an undisclosed illness. Collins has missed the last two games and was last spotted by reporters on Nov. 6. On Wednesday, he had a folded-up chair in his locker, an indication that he hadn't been at the facility.

Also, rookie cornerback Justin Coleman (hand) was not at practice, as two new practice squad players -- Chris Greenwood and Brock Vereen -- added depth at the position behind Malcolm Butler, Logan Ryan and Rashaan Melvin.

Vereen is the younger brother of former Patriot Shane Vereen.
