Buffalo Bills defense tackle Marcell Dareus is still expected to play against the Chiefs on Sunday following the murder of his 19-year-old brother, according to head coach Chan Gailey.

Dareus's brother, Simeon Gilmore, was killed in a triple homicide in Alabama over the weekend after sustaining multiple gunshot wounds during a home invasion. Here's what Gailey had to say on Dareus's weekend availability:

"I talked to him this morning," said the head coach. "I think he'll be back for Sunday's game, whether it's tonight, tomorrow or the next day I don't know. But I think he'll be here for this week. He wants to be back."

Dareus, who had one solo tackle in the Bills 48-28 loss to the New York Jets last Sunday, had 43 tackles and 5.5 sacks last season while appearing in all sixteen games in his 2011 rookie campaign. His presence is sure to make Jamaal Charles and Peyton Hillis's jobs more difficult, but it will still be encouraging to see Dareus on the field following such a senseless tragedy.
