Marcus Smith out 2-3 weeks with a hamstring injury

Eagles linebacker Marcus Smith.

Marcus Smith will miss 2-3 weeks with a hamstring injury, the linebacker said. He expects to be back for the regular season. The injury comes at a depleted position and is a setback for the 2014 first-round pick.

“I’m glad it wasn’t anything major, but it’s still something that keeps him out,” defensive coordinator Bill Davis said before practice on Friday. “It’s disappointing, probably to him more than anybody. He was really taking some growth steps and coming along, and now he’s got a setback.”

 With Smith out, the Eagles are now down their fourth outside linebacker this summer. Smith and Travis Long were strong possibilities for the No. 3 outside linebacker job. Without them, the Eagles will cross-train inside linebackers Brad Jones and Emmanuel Acho, and they will also use defensive end Vinny Curry more at outside linebacker.

“We’ll accelerate Vinny’s move out there now because of the depth,” defensive coordinator Bill Davis said. “We’re excited and Vinny’s excited about seeing him out there. We’ve worked all the offseason, and we’ve slowly leaked him in. The last couple of weeks he’s gotten more and more, and this week, we’ll give him a lot. And in the game, we’ll give him some.”

More to come after practice.
