FOXBOROUGH -- Rookie defensive lineman Michael Buchanan was back at Patriots practice, one day after a non-injury-related reason caused him to miss Wednesday's workout.
Another rookie, linebacker Jamie Collins, was not spotted in the portion of practice made accessible to the media. He was not listed on Wednesday's injury report. Two players who were -- running back Leon Washington (ankle) and defensive tackle Tommy Kelly (knee) -- were also not spotted. Both players left Sunday's game at Cincinnati with injuries.
Players were in sweats and shells.
Two other injured Patriots were spotted working out on another field. Running back Shane Vereen broke his wrist in the season-opening win at Buffalo, and was placed on the injured reserve list with a designation to return. He still has a brace on the wrist, and is eligible to return no sooner than the Nov. 18 game at Carolina. He was joined by defensive lineman Armond Armstead, who is on the non-football-injury list.
