Tampa Bay Lightning fans held their collective breaths Friday when Vezina Trophy finalist Ben Bishop went down with a knee injury in Game 1, but thankfully backup netminder Andrei Vasilevskiy was ready to calm their nerves.

Vasilevskiy made 25 saves in relief, and although it's unknown how long Bishop will be out, the Lightning crease belongs to the 21-year-old for the time being.

Fear not, Lightning supporters, it's not completely uncommon for a backup to take the reins in the playoffs.

Here are three instances when an unsuspecting goalie was thrust into the postseason spotlight:

Jussi Markkanen - 2006

Riding the momentum of a magical playoff run, the Edmonton Oilers saw their underdog lives flash before their eyes when starter Dwayne Roloson went down in Game 1 of the 2006 Stanley Cup Final.

Markkanen got the nod in Game 2 - a 5-0 loss - but the Finn turned things around. He allowed one goal in Game 3, then posted a shutout in a do-or-die Game 6. He led the Oilers to Game 7, but ultimately lost 3-1 to the Carolina Hurricanes in the championship-deciding contest.

Steve Shields - 1997

Dominik Hasek was the backbone of the Buffalo Sabres in the 1990's, leading the team to the playoffs nearly every season during his Hall of Fame career. It was a different story in 1997, however.

Hasek won his third of six Vezina trophies as the Sabres won their division, but a knee injury in the postseason's opening round saw Shields take over.

Shields helped the Sabres take down the Ottawa Senators in seven games, then remained in goal versus the Philadelphia Flyers, who ended Buffalo's run in five games with Hasek sidelined.

Matt Murray - 2016

Vasilevskiy's counterpart knows the feeling.

Murray took over for an ailing Marc-Andre Fleury, and while some wrote the Penguins off, the rookie has shined.

The 21-year-old has a .929 save percentage and 2.15 goals against average in his first taste of playoff action, and has proven to be more than adequate between the pipes.

Blink and you'll miss a terrific goal by Evgeny Kuznetsov.

The Washington Capitals forward showed impressive hand-eye coordination while representing Russia at the World Championship on Saturday, following his own shot and batting the puck out of mid-air into Switzerland's net.

The Capitals' trio of Kuznetsov, Alex Ovechkin, and Dmitry Orlov were playing their first game for Russia at the 2016 tournament.

The host country entered the game sitting in third place in Group A, with three wins and one regulation loss.

Ryan Callahan reportedly won't be disciplined further for his hit on Kris Letang.

The NHL's Department of Player Safety does not have a hearing scheduled with the Tampa Bay Lightning forward, according to Joe Smith of the Tampa Bay Times.

Callahan drove the Pittsburgh Penguins defenseman into the boards early in Game 1 of the Eastern Conference Final on Friday night.

He was given a five-minute major for boarding but was not ejected. Letang was forced to leave the game, but returned before the first intermission.

Callahan said after the game that he thought the position Letang was in made the hit "worse than it was".

One game into the Eastern Conference final and the Pittsburgh Penguins are still gauging their opponent.

Since head coach Mike Sullivan took over, the Penguins have feasted on opposition with speed and skill in transition, but the Tampa Bay Lightning beat them to the punch with the same game plan Friday in Game 1.

A breakaway goal from Alex Killorn, and a perfectly executed 2-on-1 finished by Jonathan Drouin provided Tampa Bay's margin of victory, and Pittsburgh knows they'll have to stifle those opportunities going forward.

"That's where they got all their opportunities, from transition," Penguins goalie Matt Murray told Tom Gulitti of NHL.com. "It's nothing they're doing that's overwhelming us. We're just giving them a couple too many turnovers and they're a fast, skilled group in transition. I think it's something we game to them. It's not necessarily them outplaying us. It's something that can be fixed for sure."

Pittsburgh outshot Tampa Bay 35-20, but fell victim to the Lightning striking on their mistakes, and Sullivan knows that was the difference.

"We've got to make sure that we're diligent with out decisions with the puck and in those 50-50 battles," Sullivan said. "We've got to stay above people and stay on the right side so we don't allow some of the odd-man rushes."

The Penguins haven't lost consecutive games since mid-January, and have to focus on their own game rather than becoming fixated on the strengths of the Lightning.

"I think we need to be better just understanding how they play, what it looks like," Sidney Crosby said. "We've got a better feel for that, but at the end when it's all said and done here we still have another level we've got to find if we want to win games."

Ryan Callahan didn't intend to board Kris Letang and was happy to see him return.

So said the Tampa Bay Lightning forward after Friday's Game 1, describing the incident with the Pittsburgh Penguins defenseman as unfortunate.

Callahan was handed a five-minute major penalty but was not ejected.

Still, it's expected the NHL's Department of Player Safety will take a second look with a view to potential supplementary discipline.

Following the Tampa Bay Lightning's Game 1 victory over the Pittsburgh Penguins, head coach Jon Cooper provided an update on goaltender Ben Bishop, who left the game on a stretcher with an apparent lower-body injury.

"Everything came back negative," Cooper said of Bishop's X-rays, according to NHL.com's Tom Gulitti. "So we're hoping for the best."

"He's definitely hurt," he added. "But there's nothing structurally wrong."

Cooper could not provide any description of the injury, or any timetable for how long the 29-year-old may be sidelined.

Backup netminder Andrei Vasilevskiy filled in admirably in Bishop's absence, stopping 25 of the 26 shots he faced to help the Lightning take a 1-0 series lead.

Pittsburgh Penguins defenseman Brian Dumoulin was forced to leave Game 1 of the Eastern Conference finals after being boarded by Ondrej Palat of the Tampa Bay Lightning.

Head coach Mike Sullivan did not have an update on the defenseman's status immediately following the game.

Kris Letang was also boarded earlier in the game but was able to return and is said to be fine, according to the coach.

Dumoulin is averaging over 20 minutes a night in the playoffs, with four assists in 12 games.

Jonathan Drouin continues to come up big for the team he didn't want to play for.

The young Tampa Bay Lightning forward, who publicly demanded a trade earlier this season, scored in Game 1 of the Eastern Conference finals against the Pittsburgh Penguins with a tremendous finish off the odd-man rush.

Ondrej Palat served up one of his famous saucer passes to record the assist.

The goal was Drouin's second of the postseason, and his 10th point in 11 games.

Enter Kristers Gudlevskis, who is best known for his 55-save performance for Latvia in a 2-1 loss to Canada during the 2014 Winter Olympics, but was gaining more attention on Twitter during Game 1 for his hair.

The 23-year-old made one start for the Lightning during the regular season, making 31 saves in a 1-0 overtime loss to the Chicago Blackhawks.

No one was safe early in Game 1 of the Eastern Conference finals.

The latest victim was Tyler Johnson of the Tampa Bay Lightning, who had to be helped off the ice following a knee-on-knee bump courtesy of Pittsburgh Penguins forward Chris Kunitz.

The hit came after Kris Letang was boarded but able to return, and Ben Bishop was carted off the ice on a stretcher with an apparent lower-body injury.

Johnson did not return for the beginning of the second period, but emerged from the locker room later in the period.
