Chicago Blackhawks defenseman Calvin de Haan Vincent Carchietta-USA TODAY Sports

The Chicago Blackhawks were one of the few teams left in the league without a player in the COVID protocol — until now. Calvin de Haan was added to the protocol Monday, meaning they won’t be able to get through the holiday break unaffected. Notably, de Haan missed the last two games with what was dubbed a “non-COVID illness.”

That diagnosis appears to have changed, though the team did not technically confirm that de Haan tested positive for coronavirus. Like the rest of his protocol peers, de Haan will be held out for a minimum of 10 days if he tested positive and is experiencing symptoms. That would mean he is at a minimum not available for Thursday’s game against the Dallas Stars and likely means he’s also out for Dec. 28 and 29 against the Columbus Blue Jackets and Winnipeg Jets.

While not the player he once was, de Haan is still a regular part of the Blackhawks lineup and averages nearly 19 minutes a night. He has failed to register a single point through 26 games this season.
