Redskins outside linebacker Preston Smith left today’s practice early after sustaining a shoulder injury.

“We’ll see,” said head coach Jay Gruden. “He just strained his shoulder a little bit, it’s a little weak.”

Gruden said that Smith will be evaluated tomorrow before a decision is made on him playing against the Falcons in the Redskins’ preseason opener.

The second year player had the shoulder wrapped before leaving the field.

The Redskins can ill afford any major injuries at Smith’s position. They lost Junior Galette to a torn Achilles in the days before camp started. That forced them to reverse the move of Trent Murphy from OLB to defensive end.
