When the playoffs started at the beginning of April, the Colorado Avalanche were decimated by injury. After playing just 2 games of the first round, Valeri Nichushkin was out of the lineup too.
Nichushkin was, of course, found with an intoxicated woman in his hotel room the morning of game 3 of the first-round series against the Seattle Kraken.
This whole thing seems odd, especially given the how the situation appeared. However the NHL is no stranger to doing investigations and if they feel one isn't warranted, then that's the end of it. One would thing that if the NHL is allowing him to play next season, nothing happened.
