Dallas Cowboys linebacker Caleb McSurdy will have season-ending surgery on Friday to repair a torn Achilles tendon.

"He's back in Dallas right now. He's going to have the surgery tomorrow," said Cowboys head coach Jason Garrett following Thursday's practice. "It is a tough injury. One of the things that young players, and really all players need to understand is all they can do is control what they can control. In his case, go get the surgery. Do exactly what our trainers and our medical people say in terms of his rehab and understand that you're going to be back."

McSurdy suffered the injury during Wednesday's afternoon session. The seventh- round pick in this year's draft out of Montana will also be placed on injured reserve.
