Semyon Varlamov's season is over.

The Colorado Avalanche goaltender will undergo surgery Thursday in an attempt to eradicate groin muscle issues that have kept him off the ice for long stretches in recent years, according to Terry Frei of the Denver Post.

"(Varlamov) has been dealing with groin and hip issues for some time now," said general manager Joe Sakic. "After further evaluation from our team doctors, it was determined that the best road to recovery was surgery. Doing this procedure at this time ensures that Semyon will be fully healthy for the start of training camp."

The last-place Avalanche will presumably roll with Calvin Pickard and Spencer Martin in net for the balance of the regular season.

Varlamov, a 2013-14 Vezina Trophy finalist, posted a record of 6-17-0 with a .898 save percentage in 24 appearances this season. He remains under contract with the Avalanche through to the end of 2018-19 at a salary-cap hit of $5.9 million.
