Tomlin said initial tests on Roethlisberger showed he suffered a concussion Sunday against the Cleveland Browns, but the injury should heal in time for the playoffs, the Pittsburgh Tribune-Review reported Monday.
"He is not permanently injured or scarred at this point," said Tomlin, whose team finished the 2008 season with a 12-4 record. "He just has a concussion."
Roethlisberger left the field strapped to a stretcher Sunday after being struck by Browns linebackers D'Qwell Jackson and Willie McGinest during a pass attempt. The concussion marked his third on record.
Steelers wide receiver Hines Ward also expressed confidence his quarterback would be ready in time for the team's initial post-season game in Pittsburgh in two weeks.
"Ben will be all right," Ward told the Tribune-Review. "He's going to take this whole week off and get his screws right, and he's going to come back and be prepared for the playoffs."
