This was the only game in the Stadium Series held during the 2018–19 season (as opposed to multiple games in 2014 and 2016).
Background
In 2016, the Pittsburgh Penguins and the Philadelphia Flyers worked out an agreement to play a home-and-home series of outdoors games. The first game that was planned eventually became the 2017 Stadium Series game at Heinz Field in Pittsburgh. The NHL does not usually schedule teams to appear in outdoors games in consecutive years, so Philadelphia did not host this rematch until 2019. The two archrivals had also discussed playing a neutral site game at Beaver Stadium at State College, Pennsylvania, but it never materialized, due mainly to concerns about Beaver Stadium's plumbing being unable to withstand an event in winter.
Game summary
The Flyers scored two goals with an extra attacker/goalie pulled late in the third period to tie the game at 3–3, then won it off of Claude Giroux's score at 1:59 into overtime. Jakub Voracek scored the tying goal with 20 seconds left in regulation, as well as recording two assists. Voracek's score came after James van Riemsdyk's power play goal with 3:04 left cut the Penguins' lead to 3–2.
