Ben Roethlisberger

Darrius Heyward-Bey had just beaten a pair of Ravens defenders downfield, got a hand to a Ben Roethlisberger pass, only for it to bounce away as a Ravens player fell down his leg.

Heyward-Bey bent over to his left side, removed his helmet and grabbed at the back of his right knee. A trainer hurried onto the field and examined the Steelers wide receiver's right ankle.

The receiver put no weight on his right leg, dangling his foot as he limped off the field. He was eventually carted to the locker room, the story said.
