Nick Paul scored twice, including a stunning individual goal late in the second period, as the Tampa Bay Lightning defeated the Toronto Maple Leafs 2-1 in Game 7 on Saturday.

The two-time defending Stanley Cup champions came from a goal down in the previous two games, and had to do it again on the road at the Scotiabank Arena after Thursday's overtime win to level the series.

Morgan Reilly scored for Toronto but Andrei Vasilevskiy stopped an eventual 29 shots to keep the Lightning in the game, before Paul's brace secured the series win.

The Leafs were condemned to their seventh consecutive playoff series loss, and have not made the second round since 2004. After the match, Leafs head coach Sheldon Keefe commended the reigning champions on their series win.

"They [Tampa Bay] don’t get a lot of credit because you don’t really think of them this way, but we knew coming into this series that going into third periods down against this team was going to be a challenge," he said post-game.

"They are the number-one team in the NHL when it comes to limiting chances against when up a goal in the third period. All regular season, they were that.

"That is sort of the hallmark of their success. That is championship hockey. They didn’t give us a great deal in that third period tonight. Those are the things I take away - just how hard they defend and how they prioritise defending."

In Saturday's other results, the Carolina Hurricanes won their series-deciding game at home to the Boston Bruins 3-2, while the Edmonton Oilers claimed Game 7 against the Los Angeles Kings with a 2-0 win.

Florida Panthers interim coach Andrew Brunette said his side's fighting spirit was key in a series comeback against the Washington Capitals, culminating in Friday's 4-3 victory in overtime.

It was the Panthers' third straight win after falling down 2-1 in the series, and Game 6 was closely contested throughout.

After a scoreless first period, Nic Dowd opened the scoring for the Capitals, before Ryan Lomberg answered straight back to keep things at 1-1 heading into the last frame.

Nicklas Backstrom put the home side back in front, but the 'Comeback Cats' would not lay down, with Claude Giroux and Aleksander Barkov giving the Panthers a 3-2 lead.

In the closing stages, after the Capitals had pulled their goalie to get an extra attacker on the ice, T.J. Oshie found the equaliser to send the crowd into raptures and force overtime.

But this was the Panthers' night, and Carter Verhaeghe slotted the golden goal less than three minutes into the extra period to win the game and seal the series.

It is the first time the Panthers have won a playoff series since 1996, and Brunette said the performance epitomised their season.

"I think it's what we saw all year – the resiliency of the group," he said.

"People will say we're the 'Comeback Cats' – I'm not sure that's what I see – I see a group of guys that get hit, and they don't fall down, and they start hitting back. 

"They showed that throughout the whole series, they showed it tonight. 

"We gave up a late goal – it was a heart-breaking moment that could really affect you and can kill momentum – but again, we took the punch, we stood up, and we started punching back. It epitomises the whole season for us."

Asked if finally getting an elusive series win takes the pressure off his players, Brunette said he hopes it is the case.

"I hope [the series win takes the monkey off the Panthers' backs] – especially for the guys that have been here for a while," he said.

"It probably feels really good, because they put a lot of pressure on themselves – probably too much – throughout the course of the series. They were able to find a way and pull through it.

"I think as the series went on I felt they loosened up a little bit. We were a little nervous at home the other night, but they found their mojo and got going. 

"These things – you've got to go through them a few times to really get the feel of it. You have to have heartbreaks, you have to have things not go your way, to find out how hard it is, and understand it, and be resilient. 

"When you see the reward like they did tonight, it's all worth it."

Brayden Point scored the winning goal in overtime and forced a Game 7, as the Tampa Bay Lightning secured a thrilling 4-3 victory over the Toronto Maple Leafs on Thursday.

Ondrej Palat, Anthony Cirelli and Nikita Kucherov also scored for the reigning Stanley Cup champions, but they had to battle until 1:56 remaining in overtime for Point's sealer.

The Lightning had to fight their way back from 3-2 down in the final period with their season on the line, after Leafs captain John Tavares scored twice in the second period's closing 34 seconds.

With his side dropping a lead for the second straight game, Tavares said the focus is now on regrouping as the series heads back to Toronto for the decider.

"We worked hard all year to earn home ice and we've got a great opportunity going home in front of our fans to try to close this thing out," he said.

"So just regroup here, and look forward to the opportunity. This is what the game's all about."

The Boston Bruins also forced a Game 7 after they defeated the Carolina Hurricanes 5-2, while the St. Louis Blues advanced to the second round, beating the Minnesota Wild 5-1 in Game 6.

In Thursday's final game, the Edmonton Oilers evened their series up with the Los Angeles Kings in Game 6, winning 4-2.

New York Rangers center Filip Chytil said his side were determined to keep their season alive as they came from a two-goal deficit to beat the Pittsburgh Penguins 5-3 at Madison Square Garden.

Trailing 3-1 in the series heading into the clash, the Rangers were hanging on by a thread after goals from Jake Guentzel and Kris Letang had the Penguins leading 2-0 eight minutes into the second period.

But the Rangers were not going out that way in front of their home fans, rattling off three goals in under three minutes courtesy of Adam Fox, Alexis Lafreniere and Jacob Trouba, although Guentzel's second tied it up at 3-3 going into the last period.

Chytil sent the crowd into raptures with a power-play goal just three minutes into the period, before Ryan Lindgren put the game to bed in the closing seconds.

Speaking afterwards, Chytil said there was a desperation to not go out with a whimper after being outscored 14-6 in the past two fixtures played in Pittsburgh.

"We were not happy with what happened in Pittsburgh," he said. "We just didn’t play the whole season [the] way that we played, just [to] lose games like this in Pittsburgh.

"So we just had a good meeting, good practice yesterday, and we just believed today that we’re gonna win and we’re gonna go back to Pittsburgh.

"We believed, because we should have done more… we turned momentum to our side, and that was what we need."

Fellow goalscorer Lafrieniere was also complimentary of his team for the way they handled the pressure.

"We played a good 60 minutes," he said. "We defended well and played a good all-around game.

"We did a good job of staying calm. We have to keep it going and win Game 6 – [but] we played a really good one when we needed it most."

Making matters even worse for the Penguins is the fact that Sidney Crosby was forced to leave the game after suffering an injury in the second period, with Guentzel putting it plainly how important he is to the team and the gaping hole that will be left if he cannot get up for Game 6.

"We never want to see a player like that leave, but we have to find a way," Guentzel said. "[Crosby] is the best player in the world. That's a lot of minutes other guys have to take up. Next man up."

Game 6 will head back to Pittsburgh, and if the Rangers can win it, they will earn a Game 7 at home.

Auston Matthews says his game-winner was "pretty special" after the Toronto Maple Leafs battled back from two goals down to win 4-3 over the Tampa Bay Lightning in the NHL playoffs on Tuesday.

The Maple Leafs trailed 2-0 after the first period but rallied with Matthews settling the contest with their third goal in the third period.

The win means Toronto lead 3-2 in the best-of-seven series against the reigning Stanley Cup champions.

"It was pretty special," Matthews told reporters, speaking about the goal. "To battle back from down two goals, and never losing hope and competing, that was big."

Matthews led the NHL across the regular season with 60 goals but he had not scored in the playoffs since Game 1 of the series.

Teammate John Tavares, who pulled one back during the second-period power play, praised the NHL's back-to-back Rocket Richard Trophy winner Matthews, who was also credited with seven hits.

"His whole game is all just really good," Tavares said. "When you score 60 goals, that's going to get [discussed], and how he scores it in different ways and the uniqueness of his shot in his abilities, but his all-around game is as good as anybody's in the league.

"He's going to play hard and compete because they're making it hard on him to earn his ice and opportunities, so good for him to play them hard."

The victory means Toronto are one win away from the franchise's first playoff series victory since 2004.

"I just think we needed to possess the puck a little bit more," Matthews said. "Get on top of them and be forechecking and not giving them as much time and space. We were on top of them and had our heads up to make plays."

Elsewhere, Adrian Kempe's over-time goal earned the Los Angeles Kings a 5-4 win over the Edmonton Oilers, having blown a 3-1 lead.

The goal was Kempe's second of the game, as he finished with a three-point performance. The result puts the Kings up 3-2 in the series.

The Carolina Hurricanes also moved up 3-2 in their series against the Boston Bruins with an emphatic 5-1 win after losing their past two.

Rookie Seth Jarvis scored twice and Antti Raanta finished with 34 saves.

The St Louis Blues piled on three third-period goals, all from a Vladimir Tarasenko hat-trick, to secure a 5-2 win over the Minnesota Wild to lead their series 3-2.

Patrick Marleau, the NHL's all-time leader in games played, is officially retiring after 23 seasons. 

The 42-year-old Marleau, who spent 21 seasons with the San Jose Sharks while also playing for the Toronto Maple Leafs and Pittsburgh Penguins, announced his decision on Tuesday in a piece he wrote in the Players' Tribune. 

"It's bittersweet for sure, but I have so much to look forward to," Marleau wrote. "Who knows what the world has in store for me?

"If you would have told that kid on the frozen pond that he would break a games-played record held by none other than Gordie Howe, he would have thought you were crazy.

"It was never something I aimed for; it was just me loving this game so much that I never, ever wanted to hang up my skates." 

Marleau broke Howe's games-played record of 1,767 on April 19, 2021, and finished his career with 566 goals, 631 assists and 1,197 points in 1,779 games. 

The second overall pick of the 1997 draft by the Sharks, Marleau is the most decorated player in franchise history, holding club records for games played, goals, points, power-play goals, short-handed goals and shots.

He made his NHL debut in 1997 and spent his first 19 seasons with San Jose before joining Toronto in 2017. 

During his time with the Sharks, Marleau helped the club capture six division titles and earn 17 playoff berths, although San Jose lost to Pittsburgh in six games in his only trip to the Stanley Cup Finals in 2016. In 195 playoff games, Marleau amassed 72 goals and 55 assists for 127 points. 

Marleau played in his final game almost one year ago on May 12, 2021, sitting out the 2021-22 season after not signing with a team. 

The Florida Panthers twice came back from a one-goal deficit to defeat the Washington Capitals 3-2 in overtime, tying the series at 2-2.

Heading into the contest trailing 2-1, and playing on Washington's home ice, the Panthers were put on the back foot early after T.J. Oshie opened the scoring in the first period.

Carter Verhaeghe tied things up less than 10 minutes later, before Evgeny Kuznetsov put the Capitals back in front in the third period off an assist from legendary teammate Alex Ovechkin.

With just over two minutes to play, Sam Reinhart tied it at 2-2 to force an extra period, where Verhaeghe would slot the winner five minutes in to steal the game on the road.

Speaking to post-game media, two-goal hero Verhaeghe said the result adds to the belief of what this team – dubbed the 'Comeback Cats' – can accomplish.

"We wanted to come in and have our best game of the series, and I think we did a pretty good job," he said.

"It’s just kind of a building block. We know we have another level to get to, and we’re a great team, so I think it’s just building some confidence."

Fellow goal-scorer Reinhart added that the backs-to-the-wall nature of the battle was everything he enjoyed as a competitor.

"Those are the kind of situations you want to be in as a hockey player," he said. "It’s a game that can really go either way at the end of it – we stuck with it, and we’re happy with the result."

Washington's Ovechkin – a three-time Hart Memorial Trophy winner for league MVP – was clear about the next course of action, and not overreacting to a painful loss.

"At the end, it was bad bounces and it goes in," he said. "It is going to be a tough, long series, so move on. Forget about it, move on."

It was much smoother sailing for the Colorado Avalanche, beating the Nashville Predators 5-3 to sweep their series 4-0. J.T Compher and Cale Makar both collected a pair of assists each for the Avalanche.

The Pittsburgh Penguins received a vintage performance from future Hall-of-Famer Sydney Crosby as he slotted one goal and dished two assists in his side's 7-2 win against the New York Rangers, taking a 3-1 series lead in the process.

Lastly, the Calgary Flames won a crucial Game 4 on the road against the Dallas Stars 4-1 to tie their series at 2-2, despite Stars goaltender Jake Oettinger making 50 saves.

The New York Islanders have fired Barry Trotz as head coach after a disappointing 2021-22 season.

Trotz spent four years in New York, and reached the playoffs in each of his first three, but the Islanders have struggled this season, ending in ninth place in the Eastern Conference with a record of 37-35-10.

A statement on the organisation's website on Monday simply read: "New York Islanders President and General Manager Lou Lamoriello announced today that Barry Trotz has been relieved of his duties as Head Coach."

Trotz was brought in by the Islanders in 2018 having just won the Stanley Cup with the Washington Capitals, but he was unable to repeat the feat in New York.

They were eliminated by the Carolina Hurricanes in the second round of the playoffs in 2018-19, though Trotz won the Jack Adams Award for the second time in his career that year, having also won it with the Capitals in 2016.

The Islanders were beaten by the Tampa Bay Lightning in each of the next two seasons, who went on to win the Stanley Cup on both occasions.

New York Rangers coach Gerard Gallant has defended his call to pull goaltender Igor Shesterkin after the first period as Pittsburgh Penguins ran out to a 7-4 victory in Game 3.

The visitors suffered a playoffs setback at PPG Paints Arena, as their Pennsylvanian hosts moved into a 2-1 lead in the Eastern Conference first-round series.

Shesterkin was hooked after the first period after Pittsburgh raced into a 4-1 lead and was replaced by Alexandar Georgiev.

That helped spark a turnaround for the Rangers, who clawed back three goals in the second period to move back on level terms.

But after Danton Heinen put the Penguins back in front halfway through the third period, Pittsburgh did not relinquish their lead again, with Jake Guentzel and Jeff Carter extending their advantage.

Gallant backed his decision to withdraw Shesterkin, a 2018 Olympic gold medallist, saying that it was to offer the goaltender much-needed rest after a busy schedule and thought it might provide a spark.

"It's 4-1 and you want to change momentum," he stated. "Igor has been outstanding.

"If you look at it right now, he's played 10 periods, more or less, in basically 4 and half, five days. I thought it was a good time to jump-start it.

"It was 4-1. It was totally tilted. Sometimes you spark your team with a goalie change. Igor was our MVP all season.

"I thought we'd give him a little rest tonight and hopefully spark our team. And it worked."

The Rangers will attempt to hit back in Game 4 on Monday.

Evander Kane said it is "nice to turn the page" after a "lot of trials and tribulations" as he starred in the Edmonton Oilers' 8-2 hammering of the Los Angeles Kings on Friday.

The forward registered a first career playoff hat-trick as the Oilers took a 2-1 lead in their first-round Western Conference series, celebrating a couple of rebound finishes in the second period and adding a third with 20 seconds remaining.

Kane only joined the Oilers after being waived by the San Jose Sharks in January. The 30-year-old had been suspended for 21 games by the NHL for providing a fake COVID-19 vaccination card, then broke health and safety protocols when representing San Jose Barracuda in the American Hockey League.

That followed a tumultuous offseason in which Kane was embroiled in plenty of off-rink controversy, but he feels like he is getting back on track with the Oilers.

"The beginning of the year was very tough, with a lot of different things going on in my life. It's a real credit to my family, helping me through everything – my uncle is actually in the hospital, and we wanted to have a big game for him," Kane said after the game.

"There's been a lot of trials and tribulations, but it's nice to turn the page and move forward in a positive way.

"[This is the best I've felt since joining the Oilers] for sure – I started to feel good around the 20-game mark, and I'm back to my old self."

Kane now has at least two goals in two straight games and is the 12th different Oilers player to celebrate a playoff treble.

Ryan Nugent-Hopkins and Zach Hyman scored two goals apiece as well and Kane talked up the team's abilities.

"I think our five-on-five game has gotten a lot better. Obviously our special teams has been good throughout these three games, but it's that time of year where you want to raise your game to a different level, and I think there's a lot of guys doing that right now. I like to think [I am one of them]," Kane added.

"We got up 5-0, and they came with a bit of a push in the second and scored two. You know, there's a lot of hockey left to be played. 

"They got their fans back in the building, they got some energy on the bench, but we came out and stuck with it. We had a strong third period, and we continued to push the pace, and not sit back. 

"I think that's the real key to winning – when you get leads, it's about what you do with them. Do you sit back and get comfortable, or do you continue to push, and I think we're doing a good job of that."

Pittsburgh Penguins captain Sidney Crosby was quick to back goaltender Louis Domingue, following their 5-2 loss to the New York Rangers on Thursday.

The Rangers tied their playoff series up at 1-1 after Pittsburgh's 4-3 win in triple-overtime at Madison Square Garden on Tuesday.

One of the key figures in that overtime win, Domingue was given a start by Penguins coach Mike Sullivan, but gave up key goals to Ryan Strome and Chris Keider via deflections.

Crosby backed his teammate following the loss, bringing saves he did make with Game 2 in the balance in perspective.

"The fourth was a bad bounce, a couple of tips there," Crosby said. "I thought he [Domingue] was solid. I thought he made some big saves, especially when there was a one or two-goal difference, that kept us in it."

The two-time Hart Memorial Trophy winner believes the Penguins simply need to start better and put three periods of hockey together to progress past the Rangers.

"It's the playoffs," Crosby said. "There are going to be swings of momentum but I thought that in both games, as they've gone on, we've probably gotten better. We just have to find a way to come out of the gates a bit better.

"You don't want to get down two, we've done that a couple of times now. It's not something we want to make a habit of.

"We get that late one and we had some really good chances early in the third and didn't convert, and they got a bounce. That's what it came down to."

In other NHL playoff results on Thursday, a Cale Makar goal gave the Colorado Avalanche a 2-1 overtime win over the Nashville Predators, moving to 2-0 in their series.

Meanwhile, the Dallas Stars and Florida Panthers tied up respective series with the Calgary Flames and Washington Capitals.

Tony DeAngelo saved special praise for rookie goaltender Pyotr Kochetkov after the Carolina Hurricanes defeated the Boston Bruins 5-2 on Wednesday.

Kochetkov was thrust into the spotlight for his playoff debut as the Hurricanes took a 2-0 lead in what is becoming a fiery series.

With Frederik Andersen already down, tempers boiled over as the Canes had to turn to Kochetkov after Antti Raanta was struck in the head by David Pastrnak's glove as he skated past.

The two teams traded words and big hits throughout, and defenseman DeAngelo made it clear where the Hurricanes stand with the Bruins in this series.

"We're not going to get pushed around, I guarantee you that," he said.

DeAngelo was glowing of Kochetkov's demeanour after the first-period change and his ability to keep it simple in a heated environment, making 30 saves.

"I think he's real calm," his team-mate said. "You don't see any jitters, at least in my eyes. I don't know what he's feeling inside. I'm sure he's a little nervous. Anybody would be, right?

"But I thought he was real calm in the net. He made a lot of saves, wasn't trying to do too much. He was calm. Coming into goal in the first period in a playoff game as a rookie after coming here a few weeks ago, he was really good."

Elsewhere on Wednesday, the Tampa Bay Lightning and the Minnesota Wild tied up their respective series against the Toronto Maple Leafs and the St. Louis Blues with wins.

The Edmonton Oilers also tied up their series, smashing the Los Angeles Kings in a 6-0 shutout.

Evgeni Malkin says the Pittsburgh Penguins "deserved to win" after he scored the decisive goal 5:58 into the third overtime of their 4-3 victory over the New York Rangers in the NHL playoffs on Tuesday.

The Penguins take a 1-0 lead in their Stanley Cup playoff opening-round series, where goalies Igor Shesterkin and Louis Domingue were outstanding for both sides.

Penguins back-up goalie Domingue came in for Casey DeSmith who exited due to cramping. Domingue starred with 14 saves in the second overtime and three more in the third.

"We know we can win every game if we play right," Malkin told reporters. "We play smart. We play hard. I think we deserved to win tonight."

The Rangers had led 2-0 after Andrew Copp doubled their lead in the second lead after Adam Fox's power-play goal in the first period.

The Penguins leveled it up after goals from Jake Guentzel in the second period, before Chris Kreider restored the Rangers' lead. Malkin found Bryan Rust to square the game up again, before it headed for overtime. Malkin came up with the decisive deflection.

The epic was the longest-ever NHL game played at Madison Square Garden.

On Domingue, Malkin added: "For me, I know Louis is unbelievable. He is big and he is fast. I wasn’t worried. It is hard to score on him in practice."

Washington Capitals forward Tom Wilson was injured as his side won 4-2 over the Florida Panthers in Game 1 of their series. Wilson had scored before going off with a lower-body injury.

Colorado Avalanche piled on five first-period goals as they routed the Nashville Predators 7-2 in Game 1 of their first-round playoff series.

Elias Lindholm's first-period goal proved the difference as the Calgary Flames got past the Dallas Stars 1-0.

The NHL's leading goal-scorer and MVP candidate Auston Matthews slotted home two more in the Toronto Maple Leafs' 5-0 win against the Tampa Bay Lightning in Game 1 of their playoff series.

Matthews – who is first player since 2011-12 to score 60 goals in a season – got on the scoresheet early in the second period to make it 2-0 for Toronto after Jake Muzzin's opener to close the first frame.

Mitchell Marner assisted the first Matthews goal and also set up David Kampf to make it 3-0, before he got on the scoresheet himself to make it four, capping off a brilliant second period.

Matthews scored his second goal of the game to round out the rout in the last period, with Morgan Reilly collecting his second assist in the process.

Speaking to post-game media, Matthews gave plenty of credit to the Maple Leafs' penalty-killing unit after the Lightning failed to score from five power-play attempts, as well as his running-mate Marner.

"I thought we played fast, we played through the contact," he said. "Our penalty-kill [unit] was huge tonight, I thought that brought us a lot of momentum.

"I thought [Marner] was incredible. He was all over the puck – so much poise – he's just doing his thing out there. 

"It's fun to watch, and fun to be out there with him. I know he's going to continue to elevate, so we've got to look for everybody to do that as well.

"We were able to capitalise on some chances, so I thought it was a really good effort by us. But it's a series – it's going to be a long series – and there's a really good team on the other end. 

"They'll be ready to go next game, so we've got to watch this one, learn from it, and move on to the next one."

Matthews also highlighted the energy inside the building as the Toronto crowd tries to will their team to their first series win since 2004.

"It was humming here tonight," he said. "It was just electric through all 60 minutes.

"I think that's what playoff hockey is all about, the atmosphere and everything. 

"It's been a while since we've been in front of our fans in front of a full arena in the playoffs, so there's a lot of excitement, and the guys fed off the energy."

It was a similarly dominant showing for the Carolina Hurricanes, as they beat the Boston Bruins 5-1 at home.

There were five individual goal-scorers for the Hurricanes as Seth Jarvis, Nino Niederreiter, Teuvo Teravainen, Vincent Trocheck and Andrei Svechnikov put in one each.

The St Louis Blues collected an important road win against the Minnesota Wild, scoring twice in the opening period on the way to a 4-0 result.

David Perron was the man of the hour for the Blues, capping off his hat-trick with the final goal of the game, while Torey Krug had three assists.

The most competitive game of the night was the Los Angeles Kings' trip to take on the Edmonton Oilers, escaping with a 4-3 road win.

After two action-packed periods the sides were tied at 3-3 going into the last, with a late Phillip Danault goal proving to be the difference.

The Vegas Golden Knights are reeling after a remarkable sequence of shootout defeats saw the team miss out on the NHL playoffs for the first time.

The Golden Knights went all the way to the Stanley Cup Finals in their inaugural season in 2017-18 and had reached the postseason in each subsequent year.

But that perfect record was ended by Wednesday's 4-3 shootout loss to the Chicago Blackhawks, which means Vegas can no longer overhaul the Dallas Stars in 2021-22.

That outcome, completing the 16-team line-up for the playoffs, required a sensational, unwanted streak for the Golden Knights.

The team lost three consecutive games in shootouts, including to the Stars on Tuesday, failing to score in any of the contests.

The Golden Knights went 0-for-17 across the three shootouts, with only one other NHL team ever losing three straight games via shootouts without scoring. The Florida Panthers went 0-for-9 over three games in 2011.

"I'm surprised. I'm disappointed," said coach Peter DeBoer. "I'm at the front of the line for responsibility.

"There's a lot of expectations on this team. It's not an easy thing and it doesn't feel good for anybody right now."
