"Robin Lehner will undergo shoulder surgery and miss the remainder of the 2021-22 season. Robin has done his best to battle this injury, which he sustained on February 9, and we were hopeful that rest and rehabilitation would allow him to finish the season.
He rehabbed first and was able to return to play on March 1. At times, rest and rehab worked, but ultimately Robin, in consultation with the team's medical staff, determined that was the best course of action." - Vegas Golden Knights
