Here's a look at the NFL Scouting Combine schedule for Sunday, February 26.
Quarterbacks, running backs and wide receivers will be under the microscope as they do drills on Sunday. None of those groups will be of primary concern to Steelers fans, since inside linebacker, nose tackle and guard are all higher-profile positions. But it wouldn't be at all surprising to see the Steelers take a running back or quarterback in the later rounds. With Rashard Mendenhall out, the Steelers could try to bolster their stable of backs with a draft pick. And the team's quarterback situation behind Ben Roethlisberger is unsettled.
Meanwhile, defensive linemen and linebackers -- and this is the group that will be crucial for Steelers fans -- will have psychological tests and interviews on Sunday before heading to workouts on Monday. Defensive backs will have measurements, medical exams and psychological tests on Sunday.
