NHL: 3 stories from Sunday

The Canucks won, but now await word of Ryan Miller's condition; Tuukka Rask let his frustration show; while Nathan MacKinnon achieved a personal milestone.

Here are three stories from Sunday's NHL action:

Canucks earn bittersweet win

The Canucks cruised to a 4-0 blanking of the Islanders, however they had to complete the task without the services of goaltender Ryan Miller, who left the game early in the second period following a collision with teammate Jannik Hansen.

Miller made 10 saves and Eddie Lack stopped 27 shots to combine for the shutout. Lack established a franchise record in the process by making the most saves in a relief appearance. 

The Canucks' players were appreciative of the combined effort from the goalies. 

Vancouver also created some much-needed breathing room in the Pacific Division. The Canucks sit in second place with 71 points, 10 points behind Anaheim, but they now have a three-point cushion over the Kings, Flames, and Sharks. 

Coach Willie Desjardins did not provide an update on Miller's condition after the game. 

Tuukka Rask throws a tantrum

The Bruins dominated in a 6-2 victory over the Blackhawks, thanks in large part to a four-goal outburst in the middle frame, put there were some testy moments along the way for Boston's netminder.

Late in the first period, with his team leading 2-0, Rask picked up a penalty for playing the puck outside of the trapezoid behind the net.

When Jonathan Toews scored on the ensuing power-play just before the final horn to end the first period, Rask was unable to contain his frustration.

Rask took a swing at his goal post and was whistled for slashing because his stick clipped Kris Versteeg and sent him to the ice. 

However, Rask turned away 26 of 28 shots in a winning effort. 

Nathan MacKinnon lights the lamp

The Avalanche built up a three-goal lead and held on for a 5-4 victory over the Lightning with much of the credit due to a scoring outburst by Nathan MacKinnon.

The Colorado centre ended a goalless drought that just so happened to date back to his team's previous meeting with Tampa on Jan. 17.

All in all, MacKinnon found the net three times to record his first career hat trick and now has 12 goals this season.
