Watch: MacKinnon ejected after throwing helmet at Garland

Nathan MacKinnon's clash versus the Arizona Coyotes ended early Wednesday after throwing a helmet at Conor Garland.

The Colorado Avalanche superstar was assessed four minutes for roughing and a 10-minute misconduct.

Tempers flared between the two clubs late in the third period as Colorado held a commanding 9-3 lead over its division rivals.

Avalanche head coach Jared Bednar isn't expecting MacKinnon to face any supplemental discipline for the incident.

"He might have to be a little lighter in the wallet. But I think that will be it," Bednar said, per The Athletic's Peter Baugh.

MacKinnon finished the night with two assists, two shots, and 14 penalty minutes.
