However, his status for the Steelers' next game against Green Bay is still uncertain.
The second-year quarterback was hit on the opening drive during Monday night's game against Baltimore.
"My cleat got stuck in the ground, got twisted around a little bit," Roethlisberger said. "I re-aggravated an injury that was already there."
Roethlisberger stayed in the game and directed a game-winning drive in the final minutes, setting up Jeff Reed's 37-yard field goal with 1:36 remaining to give the Steelers a 20-19 home victory. He finished 18-of-30 for 177 yards and two touchdowns with one interception.
Roethlisberger is now 18-1 as a starter in his brief NFL career, throwing for 3,804 yards with 28 touchdowns and just 13 interceptions.
