Tomas Hertl scored for the Sharks (0-1-0) in his return to Prague, where he was born, raised and played for Slavia Praha HC at O2 Arena from 2010-13 before coming to San Jose for the 2013-14 season. James Reimer made 28 saves.
"It was a pretty special moment, obviously," said David Quinn, who coached his first game for the Sharks. "He's been thinking about that for a long time. Obviously happy for him, and the team, I thought, got a little bit inspired by that. I thought they played better after that. Unfortunately, we only got one."
Each team went 0-for-4 on the power play. Saros was especially sharp early.
"He's that kind of goalie, and he's always our best penalty killer," Predators defenseman Mattias Ekholm said. "On most nights, he's our best player. Usually that happens when we win. He's just standing in there for us, and he did tonight. Super excited for him. He's a heck of a goalie, and he makes it a lot easier for us defensemen coming back there."
It was the first regular-season game the NHL has staged outside North America since 2019. The League was unable to play overseas the past two seasons due to the COVID-19 pandemic.
The Predators and Sharks will play here again Saturday (2 p.m. ET; NHLN, NBCSCA, BSSO).
"It was great," Ekholm said of the atmosphere. "Sold out. I mean, it was awesome, and that was Friday night. I can't wait for Saturday night."
Sherwood gave the Predators a 1-0 lead at 1:01 of the first period. The forward chipped in a rebound in front of the net after a shot from the right point by Ekholm. McDonagh assisted on the goal.
Hertl tied the game 1-1 at 8:36, six seconds after a San Jose power play expired, roofing the puck from just below the right circle.
