Nichushkin underwent treatment Monday for a lower-body injury, Eric Francis of Sportsnet reports.
There was no update on Nichushkin's status from the Avalanche, but the team should know more ahead of Game 4 of the Western Conference Finals on Tuesday. He logged only 8:34 of ice time in Sunday's 5-3 loss to Vegas in Game 3. Nichushkin has contributed two goals, two assists, 19 shots on net and 17 hits in 12 appearances this postseason.
