LSU freshman defensive end Isaiah Washington is expected to return to practice this week, Les Miles said Monday.
"That's good news because he has great speed and gives us quickness there," Miles said.
Washington has not practiced in at least two weeks after injuring his arm during preseason practices. Washington was seen about four days before the McNeese State game with a hard cast around his left forearm.
LSU never announced the exact injury.
"He's been humbled from his injury," said fellow DE Lewis Neal. "He's going to come back 10 times better because he's been putting in the work, and I know he's going to be great."
Washington earned a lot of praise during fall camp. He and fellow freshman Arden Key spent every split-squad practice with the veterans.
LSU essentially used only three defensive ends in Saturday's season opener against Mississippi State. Key got his first career sack while playing significantly behind starters Tashawn Bower and Lewis Neal. Sione Teuhema did play, but only a couple snaps.
Adding Washington to the rotation could help prevent late-game fatigue, though the defensive linemen said that wasn't a factor in Mississippi State's offensive success in the fourth quarter.
"We have a lot of guys that can go out there and play," said defensive tackle Christian Lacouture. "We just have to make sure they're ready to go."
The LSU defensive line produced three sacks against Dak Prescott and Mississippi State, two of those three came from the defensive end position.
Teuhema and fellow defensive end Deondre Clark did not dress for the McNeese State game. Both traveled to Starkville but Clark did not play in the game.
Miles said he expects Washington, Teuhema and Clark to have more of an impact moving forward.
"Those guys will be counted on pretty quick to play very significant football," Miles said.
