The Pittsburgh Steelers did not practice on Monday, but because they play the Baltimore Ravens on Thursday night, they are required to submit an estimated participation injury report.
According to the Monday evening report, nose tackle Steve McLendon (ankle) and cornerback Curtis Brown (knee) are both listed as out. Brown has not yet been placed on injured reserve, but that move will be forthcoming prior to Thursday.
Had the Steelers practiced, linebacker Stevenson Sylvester (hamstring) would have been limited while defensive end Brett Keisel (foot), safety Shamarko Thomas (ankle) and linebacker LaMarr Woodley (calf) would likely have been full participants.
Head coach Mike Tomlin addressed the status of each of these players during his Monday press conference and you can read what he had to say here.
The team is expected to practice on Tuesday.
