CALGARY, Alberta — Connor Bedard had a goal and three assists, Spencer Knight stopped 33 shots for his first shutout of the season and the Chicago Blackhawks beat the Calgary Flames 4-0 on Friday night.

Tyler Bertuzzi scored twice and Andre Burakovsky also had a goal for the Hawks, who won their second straight after losing three in a row. Knight had his sixth career shutout.

Hawks center Frank Nazar left in the first period with an unspecified injury and did not return. Coach Jeff Blashill said after the win that Nazar is day to day and did not rule the forward out for Sunday’s game against the Red Wings in Detroit.

On the heels of his third-period hat-trick Wednesday at Vancouver, Bertuzzi’s opening goal with 7:28 remaining in the first gave him four goals in two periods. The score remained 1-0 until the Hawks put the game away with a three-goal third.

The Bedard-to-Bertuzzi combination struck again at 1:11 in the third period to give the Hawks a 2-0 lead. On a 2-on-1, Bedard sent a perfect pass across that Bertuzzi one-timed into the top corner.

Bedard set up Burakovsky at 7:56, then scored unassisted with 1:59 remaining for his ninth of the year.

At the 12:57 mark of the first period, Nazar set himself up to prepare to rebound Connor Murphy’s shot. Flames left winger Joel Farabee made contact with Nazar, who fell awkwardly to the ice.

Nazar was slow to skate to the bench and went back to the locker room, and the Hawks announced he would not return. He posted 3:19 of ice time before the injury.

Farabee and Colton Dach dropped gloves shortly after the Nazar injury. More scuffles ensued in the second period as tensions rose between the teams.

Nazar, 21, who signed a seven year, $46.13 million extension this summer, has five goals and six assists with a plus-3 rating this season.

Dustin Wolf had 23 saves for the Flames, who were coming off a season-high five-goal outburst in a win over the Columbus Blue Jackets on Wednesday.

The Flames, held to fewer than two goals goals for the sixth time, are the league’s lowest-scoring team at 2.19 goals per game. They also sit last in the NHL’s overall standings.
