MIAMI (Reuters) - Pittsburgh Steelers quarterback Ben Roethlisberger is rated as "questionable" for Sunday's crucial National Football League game against the Baltimore Ravens after suffering a shoulder sprain in Thursday's win over the Kansas City Chiefs.
"That is all of the information I have at this point," said coach Mike Tomlin during his Tuesday press conference.
"He is being evaluated. Obviously this injury puts his participation in the questionable category for this week. I will have more information as I get it, as the week unfolds," he added.
Roethlisberger was taken out and replaced by back-up Byron Leftwich after taking a big hit on the opening drive of the second half.
The burly quarterback, a two-time Super Bowl winner, left the stadium with his arm in a sling.
Leftwich, playing in his first regular season game in almost two years, completed 7 of 14 passes for 73 yards.
The loss of Roethlisberger would be a major blow for the Steelers (6-3) who trail the Ravens (7-2) in the AFC North.
After facing the Ravens at home, Pittsburgh have another divisional game at the Cleveland Browns before traveling to Baltimore for the return game on December 2.
