Pittsburgh Steelers head coach Mike Tomlin said in his post game press conference following the teams\’ 38-7 preseason win against the Buffalo Bills that rookie right guard David DeCastro suffered a potentially severe right knee injury and that he is scheduled to have an MRI when the team gets back to Pittsburgh. DeCastro reportedly left the Steelers locker room on crutches with a brace on his injured right knee per Ken Laird.

DeCastro injured the knee on the Steelers second drive and laid on the field in obvious pain. He was carted off to locker room for further examination.

The Stanford rookie was the Steelers first round draft pick this past April and had solidified his place as a starter on the Steelers offensive line prior to the injury happening. He will likely be lost for the year and placed on injured reserve. Ramon Foster replaced DeCastro in the lineup and will be the starter moving forward.

Tomlin also reported after the game that right defensive end Brett Keisel suffered a mild high ankle sprain in the game. That injury figures to keep him sidelined next week in the preseason finale versus the Carolina Panthers and hopes are that he will be ready for the opener at Denver.
