Updating AFC East injuries

Let's take a look at key injuries this week in the AFC East.

Buffalo Bills: Starting defensive end Mark Anderson will be out Sunday and indefinitely with a knee injury. This is a big blow to Buffalo, which is not getting the pass rush it expected. Bills starting defensive tackle Kyle Williams also missed his second straight practice Thursday, which is a concern. Williams told the team website that he will play Sunday against the Arizona Cardinals.

Miami Dolphins: The Dolphins continue to have concussion issues with running back Daniel Thomas, who missed practice on Wednesday and Thursday. This is a concern, considering he’s suffered two concussions already this season. Look for Miami rookie running back Lamar Miller to get increased playing time Sunday against the St. Louis Rams. Cornerback Richard Marshall also missed his second straight practice with a back injury. His chances look slim to play on Sunday. Dolphins starting running back Reggie Bush (knee) and defensive back Nolan Carroll (Achilles) practiced in a limited role Thursday.

New York Jets: The Jets are banged up. Backup safety Eric Smith injured his knee in practice this week, and Jets coach Rex Ryan said Smith will not play Sunday against the Indianapolis Colts. The good news is tight end Dustin Keller (hamstring) and receiver Stephen Hill (hamstring) are both practicing and expected to play. That should boost the offense. Ryan also is optimistic about Pro Bowl center Nick Mangold (ankle) playing. Defensive linemen Sione Pouha (back) most likely will miss Sunday’s game with a bad back. Pouha hasn’t practiced Wednesday or Thursday.

New England Patriots: Backup receiver Julian Eldelman returned to practice Thursday. He’s been out for about two weeks with a hand injury. Starting safety Steve Gregory (hip) missed practiced on Wednesday and Thursday and looks doubtful to play against the Seattle Seahawks. Backup linebacker Tracy White (foot) also missed his second day of practice.
