Peterka extended the lead to 3-1 at 11:33 with a snap shot set up by Byram.
“I was just super excited to get back in the lineup, obviously,” Peterka said. “With concussions, it’s always good to maybe get the extra days. ... So obviously, on one hand, it was frustrating. But on the other hand, I knew that the season is long and I’d rather miss one or two more games here than half a season.”
Blomqvist replaced Jarry, who has allowed 12 goals on 72 shots (.833 save percentage) this season, following the goal.
“I think [Blomqvist] played a huge role,” Penguins coach Mike Sullivan said. “I thought he made some huge saves when he came in. We didn’t play the tightest game out there. It wasn’t the cleanest game from our standpoint. He made some big saves.”
Drew O'Connor cut it to 3-2 with a short-handed goal at 9:12 of the second period with a wrist shot on a 2-on-1. The goal was upheld after Buffalo challenged for offside.
Jesse Puljujarvi tied it 3-3 at 15:20 on a backhand from the slot.
