Alex Ovechkin of the Washington Capitals became the third player in NHL history to record eight or more 50-goal seasons Saturday night -- a list topped by Mike Bossy and Wayne Gretzky, who each had nine.

The Arizona Coyotes have signed Nick Schmaltz to a seven-year contract extension.

Financial terms of the deal announced Saturday were not disclosed.

The Lightning have signed head coach Jon Cooper to a multi-year contract extension today, vice president and general manager Julien BriseBois announced. Cooper was named the eighth head coach in franchise history on March 25, 2013 (six years ago yesterday) and is currently the NHL’s longest tenured coach. He is the franchise’s all-time leader for wins with 301.

“I am very pleased to announce Jon’s extension today,” BriseBois said. “His ability to forge impactful relationships with everyone from players to staff has been a trademark of his tenure with the organization and he is the absolute best coach for our hockey team. Coop’s ability to develop a strong culture while continually adapting has been a big part of the team’s success. He has helped set high standards for our organization with his unrelenting drive for excellence. I would like to thank Coop and his family for their continuous commitment to the organization, as well as to the Tampa Bay community, and I look forward to working in partnership with Jon for years to come.”

The Boston Bruins have signed Zdeno Chara to a one-year contract extension.

Chara, 42, will earn a base salary of $2 million with $1.75 million in performance incentives.

Currently playing in his 21st season, Chara ranks sixth in franchise history in games played (948).

Washington Capitals goalie Braden Holtby has pulled out of Monday's scheduled visit to the White House in celebration of the team's 2018 Stanley Cup championship.

Holtby is the most high-profile member of the team to decline the invitation.

"It's one of those things you have to think about, but for me, I have to stay true to my values. I'm going to respectfully decline the offer," Holtby said.

"It's a tough situation for everyone, to be forced into making a decision. You're a team. You want to stick together, no matter what. I hope everyone kind of blows it away -- that you don't worry about who goes and who doesn't. For me, it's just a personal thing. I believe in what I believe in. In order to stick to those values, I have to do what I think is right, but that doesn't make a difference in anyone else's decision. We stick by every teammate and their decision."

Holtby was the goalie for all 16 wins in the Capitals' playoff run, leading the NHL postseason with a 2.16 goals-against average.

The truck driver who pleaded guilty in causing the Humboldt Broncos bus crash has been sentenced to eight years in prison.

It's the longest dangerous driving sentence ever in Canada for a case that didn't involve alcohol.

Jaskirat Sidhu's sentence was announced on Friday in a Saskatchewan court by Judge Inez Cardinal, who said: "Nothing can turn back the clock. The collision was avoidable."

On April 6, 2018, the Humboldt Broncos -- a junior hockey team of players ages 16 to 21 -- were en route to a playoff game when their bus collided with Sidhu's truck, which was carrying peat moss. The 16 dead included 10 players as well as the team's head coach.

The Chicago Blackhawks and Philadelphia Flyers will play their 2019-20 season-opening game on Oct. 4 in Prague, Czech Republic.

Both teams will hold their training camps in Europe and then play a number of exhibition games.

The NHL also announced that the Buffalo Sabres will play two games against the Tampa Bay Lightning in Stockholm, Sweden, on Nov. 8 and 9 as part of the 2019 NHL Global Series Challenge.

Lightning defenseman Dan Girardi is out indefinitely with a lower-body injury.

The team announced Girardi's status Wednesday before visiting the defending Stanley Cup champion Capitals. Girardi has missed the past five games.

The Boston Bruins won 2-1 in overtime against the Columbus Blue Jackets on Saturday after receiving a pregame speech from Conor McGregor.

Brad Marchand scored the game-winner a few minutes into overtime and paid tribute to McGregor by doing a rendition of the MMA fighter's walk after he scored.

"Yeah, I kind of wanted, was hoping to score just to do it before the game," Marchand said of copying McGregor's entrance into the ring. "It's not every day you have an icon here in the room. I just wanted to have a little fun with it."

McGregor spoke to the team before the game and after.

"He's an incredible guy, very energetic," Marchand said. "He was humble. He was happy to be here. He's expressed that to everyone. It was an honor to meet him. It was great to have him here. It's something we'll remember."

The Detroit Red Wings recalled Brian Lashoff from Grand Rapids of the AHL.

The Red Wings host the New York Islanders on Saturday. The defenseman was recalled under emergency conditions.

Lashoff hasn't played for the Red Wings yet this season. He has no goals and 11 assists in 44 games for Grand Rapids.
