The Steelers have suffered their second injury along their offensive line Sunday night, as Sunday Night Football sideline reporter Michelle Tafoya said right guard Ramon Foster is questionable to return with an "eye issue."
Right tackle Marcus Gilbert went down in the second quarter with a knee injury. No further word has been reported.
Rookie RT Mike Adams is in for Gilbert, and Doug Legursky is in for Foster.
The Steelers do not have any offensive linemen left. They dressed the five starters, Adams and Legursky. If either Adams or left tackle Max Starks were to go down, tight end Heath Miller would likely fill in. If a guard went down, the Steelers would have to get creative.
It's Adams' first regular season work but Legursky is an on-again-off-again starter at both guard positions and center in the past.
The Steelers just converted a 4th-and-short in the third quarter, leading the Broncos 10-7.
