The undefeated Pittsburgh Steelers will be down another key defensive contributor when they travel to face the Dallas Cowboys this weekend.
Steelers defensive end Tyson Alualu is out for Sunday’s game, as he continues to recover from the MCL strain he suffered in Pittsburgh’s win over the Baltimore Ravens last week.
Alualu has 16 total tackles, three tackles-for-loss and a sack this season. He is expected to be replaced by defensive end Isaiah Buggs, who was a full participant Friday after not practicing Thursday and being limited Wednesday with an ankle ailment.
Slot corner Mike Hilton (shoulder) and offensive lineman Stephen Wisniewski (pectoral) are both listed as doubtful to play against the Cowboys.
Hilton has missed the last two games with the shoulder injury that he suffered Week Six against the Cleveland Browns. He was limited all week in practice.
Hilton is still second on the Steelers with 27 solo tackles. He also has five tackles-for-loss, three sacks, an interception and a fumble recovery this season.
Wisniewski was activated off the injured reserve list on Wednesday. He has not played since injuring his pectoral in the Steelers’ season-opening win over the New York Giants. Wisniewski did not practice Wednesday or Thursday, but he was limited on Friday.
Tight end Vance McDonald is questionable for Sunday with an illness that kept him off the practice field on Friday.
There appears to be no question that defensive end Cam Heyward will be full-go in Dallas, as he was a full participant on the practice field all week.
Reserve safety Jordan Dangerfield (quadricep) will also be good-to-go Sunday after practicing all week. He injured the quad in Week 7 at Tennessee, and missed the Baltimore game.
