Gregory, Collie, Bolden not at practice

FOXBOROUGH, Mass. -- Starting safety Steve Gregory, who broke his thumb against the Steelers in Week 9, according to ESPN's NFL Insider Adam Schefter, was one of three players not spotted at the start of practice on Tuesday, conducted in full pads on the practice fields outside Gillette Stadium.

Running back Brandon Bolden, who has dealt with a knee issue this season, was not spotted, nor was wide receiver Austin Collie, who left Sunday's game with a knee injury and did not return.

On the other end of the spectrum, defensive end Rob Ninkovich was on the practice field after leaving Sunday's game due to a foot injury.

Cornerback Aqib Talib (hip) and running back Shane Vereen (wrist) were once again on the practice field as well.

Two players, a wide receiver wearing number 16 and a running back wearing number 35, were also spotted on the practice field. The team had just one open roster spot -- a practice-squad opening -- as of Tuesday morning, meaning a spot would need to be created for one of those two players. More information to come as it is received.

Before practice began, the Patriots announced that wide receiver Josh Boyce, fullback James Develin, cornerback Logan Ryan and Gregory had been named last week's practice players of the week.
