Arizona Coyotes center Zac Rinaldo was handed a six-game suspension for punching Colorado Avalanche defenseman Samuel Girard.
The NHL announced on Wednesday that Rinaldo has been banned for six games for punching Girard during Arizona's 6-2 win over the Avalanche on December 23.
After a violent collision with Avalanche center Nathan MacKinnon, Rinaldo decked Girard and knocked him out with a single punch.
The punch ignited an ugly brawl and the NHL said Rinaldo's suspension for a punch to an unsuspecting opponent.
Rinaldo, 27, has been suspended 25 games in six NHL seasons. In 306 career NHL games, Rinaldo has scored 11 goals.
