PITTSBURGH -- The Pittsburgh Steelers will likely face the league's best rushing offense without a key component up front.
Rookie nose tackle Javon Hargrave (concussion) did not participate in practices all week and is listed as doubtful for Sunday's game at the Buffalo Bills. In Pittsburgh, players who don't practice all week rarely play in the subsequent game, regardless of status.
Hargrave was coming off sacks in back-to-back games before suffering a concussion in last week's 24-14 win over the New York Giants.
Fourth-year nose tackle Dan McCullers told PennLive.com that he's "going to get that start."
The Steelers also are expected to test out kicker Chris Boswell (questionable, abdomen) on Sunday morning. They have veteran kicker Randy Bullock ready just in case.
Offensive guard Ramon Foster (chest) and running back DeAngelo Williams (knee) are questionable.
