Roethlisberger, who was not expected to play Sunday, entered the game early in the first quarter when starter Landry Jones was injured and led the Steelers to a 30-9 victory over the Cleveland Browns at Heinz Field.
"I drank a lot of milk," Roethlisberger said after the game. "It kind of surprised me and everyone else because I was in a boot. On Monday, my foot was basically black and blue. It's more than just me. It's the training staff -- John Norwig and the doctors and everyone. We were tireless in our rehab and trying to get ready. It was a day-by-day process, and I was just telling coach how I felt."
Roethlisberger, who sprained his foot the week before against the Oakland Raiders, was 22 of 33 for 379 yards and three touchdowns on Sunday. He threw for 286 yards and two touchdowns in the first half alone.
Steelers coach Mike Tomlin praised Roethlisberger's effort.
"I thought Ben Roethlisberger did a nice job of administering the offense on little to no reps of preparation," Tomlin said Sunday. "Tip of the cap to him to be able to do that, but he is a veteran and that experience showed up for us in a positive way."
Roethlisberger had his 41st 300-yard passing game of his career and his third against the Browns in 21 games. He passed Kerry Collins and moved into 13th place on the NFL's list for all-time passing yards. Big Ben now has 40,944 yards.
