Report: Big Ben suffered ankle sprain
Roethlisberger suffered the injury to his left leg during the Steelers' 14-3 win over the Cleveland Browns Thursday night.
"I thought my leg was broken, honestly," Roethlisberger said after the game. "It's one of the most painful things I ever felt."
Roethlisberger convinced Steelers head coach Mike Tomlin to let him take the field following halftime after X-rays revealed his bones were still intact.
The Pittsburgh signal caller's teammates rallied behind him in the second half, helping stave off a determined Cleveland defense in a tight, low-scoring division battle.
Roethlisberger is expected to wear a walking boot to protect his ankle over the weekend and will be re-evaluated next week, according to the source.
