PITTSBURGH -- The Philadelphia Eagles are the most dangerous team in the league -- in pregame warmups.

Eagles kicker Caleb Sturgis will miss Thursday night's game against the Pittsburgh Steelers with a concussion after a pregame punt hit him in the head.

Sturgis, who's competing with Cody Parkey for Philly's top kicking job, did not have his helmet on when the punt struck him.

Sturgis is in his second season with the Eagles after spending two years with the Miami Dolphins.

Sturgis is 73-of-93 for his career, including 18-of-22 last season.
