Buffalo Bills defensive tackle Marcell Dareus left Sunday's 16-6 win over the Dallas Cowboys with a neck injury, according to head coach Rex Ryan.

Injured in the first half, Dareus was spotted holding his left shoulder prior to leaving the game. He was originally listed as probable to return with a shoulder injury, but was eventually downgraded to questionable, and then to out, as the game continued.

After the game, Ryan told reporters that Dareus had actually suffered a neck injury, and that part of the reason he did not return to the game was because he had lost a good deal of feeling in his hand.

"He doesn’t have a lot of feeling in his hand," said Ryan. "He’s down with a neck and we’ll see the extent of that as we go."

Dareus' status will be of particular interest as the Bills prepare for their season finale against the New York Jets this week. Last week, Dareus was revealed as one of four Bills players that are Pro Bowl alternates for their efforts in 2015.
