Steelers' Roethlisberger hurts broken thumb

Steelers quarterback Ben Roethlisberger didn't finish Thursday's practice after hurting his right thumb. It happened when he hit his right hand (and broken right thumb) on a helmet while throwing a pass, according to The Pittsburgh Post-Gazette.

Roethlisberger, who spent the rest of practice watching with an ice wrap on his right hand, told the paper that he expects to be fine. His offensive coordinator agreed.

"A little sting on it, nothing major," Bruce Arians told reporters, via The Post-Gazette. "Just ice it down. The last period was mostly runs, just get it healed up properly."

The thumb injury didn't affect Roethlisberger despite the fact that he passed for a season-low 193 yards last Sunday. He didn't appear to have any problems throwing the ball in Kansas City, and it looked like he threw with the same velocity.

An injury hasn't forced Roethlisberger to miss a game since November 2009, when he suffered postconcussion symptoms. A look at Roethlisberger's history of injuries:

2005: Broke right thumb and tore cartilage in right knee

2008: Separated right shoulder

2009: Suffered postconcussion symptoms

2010: Broke nose and fractured bone in right foot

2011: Sprained left foot and fractured right thumb
