Vegas Golden Knights goalie Robin Lehner is undergoing season-ending surgery due to a lower-body injury, sources told ESPN on Friday.

Lehner first suffered the injury in a March 8 loss to the Flyers in Philadelphia. He left the team's road trip to receive more testing after the initial injury and missed Vegas' next several games.

Lehner returned on April 3, and posted a 2-2-1 record with a 3.21 goals-against average and .889 save percentage.

On Wednesday, Lehner was pulled after the first period against the Capitals after allowing one goal on 13 shots. The Golden Knights went on to beat Washington 4-3 in overtime but remain two points out of a playoff spot with four games remaining.

Lehner had also been dealing with a shoulder injury this season.

Logan Thomas will assume the starting goaltending position for Vegas.
