Having already lost center Fernando Velasco for the season, the Steelers could be without two more offensive linemen for a game Sunday against the Miami Dolphins at Heinz Field.
Coach Mike Tomlin said Tuesday that left tackle Kelvin Beachum (sprained knee) and guard David DeCastro (left foot) will be limited in practice this week and are questionable for the Dolphins.
Also, backup left tackle Mike Adams (left ankle) will be limited in practice, too, but Tomlin indicated he has a chance to play.
“We’ll make do as we always do,” Tomlin said. “We’ll start with the healthy people. We acknowledge there are some issues in that area.”
Defensive end Brett Keisel, who has been bothered by plantar fasciitis, had a setback, however, and will not play against the Dolphins, Tomlin said.
Tomlin said running back Le’Veon Bell, who had a concussion against the Baltimore Ravens, appears to be OK and could play against the Dolphins. Bell will be monitored this week per their usual concussion protocol.
Outside linebacker LaMarr Woodley (calf), who has missed the past three games, worked partially in practice Monday and is listed as a starter on the team’s depth chart for the Dolphins game. But Tomlin was vague if Woodley would return against Miami.
Velasco, who ruptured his Achilles tendon in the fourth quarter against the Ravens, was placed on injured reserve. He will be replaced by Cody Wallace.
“I have no problem expecting Cody Wallace to play quality football,” Tomlin said.
As additional insurance, the Steelers signed center/guard David Snow. The Buffalo Bills signed Snow as an undrafted rookie in 2012. He started two games, spending part of the time on their practice squad. They released him Aug. 30.
They also placed tackle Rashad Butler on the team’s exempt list and signed cornerback Brandon Jones to their practice squad.
Butler signed Saturday with the Steelers but the team announced he had left Monday for personal reasons. He remains under contract after they received a roster exemption.
