Despite losing 213 man-games to injury, the Penguins (32-14-5) appear to have weathered the worst. They aren't at full strength with forwards Jake Guentzel (shoulder), Nick Bjugstad (lower body) and Dominik Kahun (concussion) and defenseman Brian Dumoulin (lower body) out, but that hasn't slowed them down.
Pittsburgh, 18-5-1 in its past 24 games, has climbed to fourth in the NHL and second in the Metropolitan Division with 69 points, six behind Washington (35-12-5).
"They had Sid out for two months there and they kept winning," said Capitals forward Carl Hagelin, who played for the Penguins for four seasons and won the Stanley Cup with them in 2016 and 2017. "I think we know they're well-coached, they're a good team, and it's going to come down to determination, I think, and will."
Pittsburgh and Washington will play each other four times over the next seven weeks. Those games likely will have a big impact on the division race and seeding for the Stanley Cup Playoffs.
"They're a real good team. They're having a great year," Penguins coach Mike Sullivan said. "We believe we're a pretty good hockey team too. Just going to continue to try to get better. We're going try to win the game right in front of us. We'll see where it takes us."
Rookie goalie Ilya Samsonov, who has won his past 11 decisions, will start for the Capitals over veteran Braden Holtby, the 2016 Vezina Trophy winner voted as the League's top goalie who helped Washington win the Stanley Cup in 2018. The Penguins did not announce their starting goalie, but it's possible Tristan Jarry will play a third straight game. That would put Matt Murray, the goalie when the Penguins won the Stanley Cup in 2016 and 2017, on the bench.
But the spotlight, as always, will be on Ovechkin and Crosby, who will play against each other for the 50th time in the NHL regular season. Crosby and the Penguins are 30-17-2 against Ovechkin and the Capitals.
"When you go through that time when they both entered the League and the head-to-head rivalry, it doesn't go away," Reirden said. "There were maybe some years in the middle there where it kind of started to lose a little bit of its luster. But now I think it's back more than ever, especially with their success of winning those Cups recently and our ability to win our first Cup (in 2018) and now our desire to get back to doing that again.
"But it clearly triggers upon Sidney Crosby and Alex Ovechkin as the main stars. There's lots of stories beneath that, but the rivalry is outstanding and it's amazing for hockey and I think will forever be remembered just like you talk about [Larry] Bird and Magic [Johnson in the NBA] or different rivalries that have gone on in sports."
