WASHINGTON -- Colorado Avalanche star Nathan MacKinnon has cleared NHL coronavirus protocols and could make his season debut against the Washington Capitals on Tuesday night.

MacKinnon tested positive for the coronavirus last week and had been in the league's COVID-19 protocols since Oct. 12. The three-time MVP finalist did not travel with the team Monday because he did not have the requisite number of negative coronavirus tests to be considered available.

Coach Jared Bednar said on his weekly radio show on Denver's 92.5-FM that MacKinnon flew by himself Monday night. Under rules agreed to by the league and the players' association, MacKinnon needed to test negative twice to be cleared to play.

MacKinnon, 26, missed Colorado's first two games of the season. Because he is vaccinated, the 26-year-old's absence was considered a hockey-related injury and he was paid during his time away.

Commissioner Gary Bettman said last week that the NHL had only four unvaccinated players out of roughly 700 on active rosters. He acknowledged the pandemic will still be a factor this season, as vaccinated players are expected to test positive and miss some games, and stressed the need for vigilance.
