Injury concerns on D-line

FOXBOROUGH, Mass. -- The Patriots are currently practicing inside Gillette Stadium, and the team's injury concerns along the defensive line were highlighted as starters Vince Wilfork (foot) and Ty Warren (ankle) were not present for the start of the session.

Wilfork, a key to the team's run defense at nose tackle, and Warren, a powerful left end, also missed practices on Wednesday and Thursday.

If Wilfork does not play Sunday, rookie Myron Pryor would be a top candidate to replace him. But Pryor is also ailing, missing last Sunday's game with a chest injury. First-year player Titus Adams, who was promoted off the practice squad last week, played the nose when Wilfork left Sunday's win over Carolina. Rookie Ron Brace is another possibility.

At left end, the Patriots would likely turn to five-year veteran Mike Wright if Warren can't play. Warren played last week, but like Wilfork, did not finish the game.

In other injury-related news, quarterback Tom Brady was present for the start of practice today. Brady, who is battling through rib and right finger injuries, had missed Wednesday's practice and was limited in Thursday's session.

Veteran running back Fred Taylor (right ankle), who missed Thursday's practice, was also present for the start of today's practice.

Media members were present at the practice for only stretching drills.
