ORCHARD PARK, NY - Once again, the Buffalo Bills have a lengthy injury report this week.

At the top of the list is running back LeSean McCoy. He did not practice Thursday because of a hamstring injury he suffered early last week. His status for Sunday's game against the Patriots is still up in the air.

"I guess with that it's probably similar to last week. We'll see how he progresses these next couple of day," said head coach Rex Ryan.

McCoy left practice early last Wednesday, missed Thursday's practice but returned on Friday. He was ruled a game-time decision and ended up playing at Miami. McCoy eventually left the game in the second half after feeling pain in his hamstring.

McCoy's injury is cause for concern because he dealt with hamstring pain last year, but offensive coordinator Anthony Lynn doesn't think it is that severe.

"It's nothing like last year. Last year, the hamstring was worse. I don't think he re-injured it or anything like that. He just felt some tightness and felt it wasn't worth it."

McCoy is just one of many players dealing with injuries. Here is the full injury report from Thursday:
