FOXBOROUGH, Mass. -- Starting right tackle Sebastian Vollmer, who didn't play in the second half of Sunday's 23-3 win over the Buccaneers after injuring his foot, was not present for the start of practice Wednesday.

The Boston Herald reported that Vollmer has a sprained foot.

In Vollmer's absence Sunday, third-year player Marcus Cannon stepped in at right tackle. The Patriots' depth would also get a boost if veteran Will Svitek, a swing tackle and guard who missed the first three games with a knee injury, returns to action. Svitek, the former Atlanta Falcon, appears to be making progress.

Special teams captain Matthew Slater (wrist) was the only other player not spotted at the start of practice, in which reporters saw jogging and agility drills.

That meant tight end Rob Gronkowski (left forearm/back) and receiver Danny Amendola (groin) were working with teammates, as they did on a limited basis the last two weeks. Amendola, in particular, seemed to be moving better than he did last week as he aggressively worked his way through the bags in agility drills.

The Patriots' official participation/injury report, which will detail the level of participation of each player in practice, will be released around 4 p.m. ET.
