Steelers rookie guard David DeCastro suffered a right knee injury in the first quarter of the team's preseason game in Buffalo this evening. On Pittsburgh's second offensive drive of the game, DeCastro had his right leg bent underneath him while taking on a defender during a pass play near Pittsburgh's own goal line. DeCastro was in obvious pain as he was being attended to by Steeler trainers and medical personnel and eventually had to be carted off the field.

DeCastro had just gone into the game at right guard in place of Ramon Foster right before the injury occurred. The extent of DeCastro's injury is not known at this point, and the official word coming from the Steelers sideline is a right knee injury.

There was great excitement when DeCastro fell to the Steelers in the first round of this past April's draft, and there are already high hopes for the young guard from Stanford..

Hopefully Steelers head coach Mike Tomlin will shed more light on DeCastro's injury before the night is over.
