Big Ben blames turf for DeCastro's injury

Ben Roethlisberger doesn't know the severity of right guard David DeCastro's injury, but the Steelers quarterback believes he knows the cause.

Roethlisberger is blaming the playing surface at Buffalo's Ralph Wilson Stadium.

"This is a great field, but it's FieldTurf, and it's just killing guys because they can't get their feet out of the ground," Roethlisberger told the NFL Network, "and it's just another reason we should get rid of FieldTurf."

Unfortunately for Roethlisberger and the Steelers, they are going to play half of their eight road games this season on artificial surfaces: Cincinnati (FieldTurf), New York Giants (FieldTurf), Baltimore (Sportexe Momentum turf) and Dallas (Matrix RealGrass artificial turf).

The Steelers, though, have lost more players to severe knee injuries on grass in the past year. Running back Rashard Mendenhall injured his knee in last regular season's finale in Cleveland. Nose tackle Casey Hampton and offensive tackle Max Starks hurt their knees in the playoff game in Denver. And fullback David Johnson blew out his knee in the preseason opener in Philadelphia.

Maybe it's safer for the Steelers to play on FieldTurf.
