TORONTO — Jeff Petry scored 5:33 into the third period as the Montreal Canadiens rallied from two goals down and beat Pittsburgh 4-3 in Game 3 on Wednesday night, pushing the Penguins to the brink of elimination in the best-of-five series.

Shea Weber had a goal and two assists for Montreal, Paul Byron added a goal and an assist, and Jonathan Drouin also scored. Ben Chariot also had had assists.

Carey Price stopped 30 shots for the Canadiens — the 12th seed in the Eastern Conference as part of the NHL’s 24-team restart to its pandemic-delayed season. Montreal can advance to the normal first round with 16 teams with win in Game 4 on Friday.

Patric Hornqvist, Jason Zucker and Teddy Blueger scored for fifth-seeded Pittsburgh, which led 3-1 after Blueger’s goal 5:34 into the second. Matt Murray finished with 27 saves.

Canadiens forward Brendan Gallagher suited up after briefly leaving the Penguins’ 3-1 victory in Game 2, but was clearly laboring at times with an undisclosed lower-body injury.

Drouin pulled the Canadiens to 3-2 at 10:13 of the middle period when he redirected Chiarot’s point shot past Murray.

Byron tied it with 4:10 left in the period, just seconds after a penalty on Pittsburgh’s Evgeni Malkin expired. Byron deftly moved Nick Suzuki’s rebound from his skate to his stick and sneaked a second-effort wraparound just over the goal line.

Joel Armia nearly gave Montreal the lead early in the third but his one-timer pinballed around the crease during a power play. However the Canadiens kept up the pressure, and Petry, who provided the overtime winner in Game 1, roofed a shot past Murray’s ear from a sharp angle for their second lead of the game.

The Penguins, who had the seventh-best record in the NHL when the season was suspended in mid-March, pushed as the period wore on, with Price denying Kris Letang down low.

Pittsburgh went on the power play with 3:32 left in regulation, but Price handled Sidney Crosby’s one-timer comfortably without giving up a rebound on the only shot against.

The Penguins pulled Murray and continued to press, but weren’t able to get the equalizer.

Montreal jumped on the scoreboard first in front 4:57 into the game as Weber fired his third shot of a chaotic sequence by a down-and-out Murray.

With the Canadiens already down a man, Weber buried Hornqvist in the corner and was going to be assessed a penalty. Montreal’s captain seemed to be waiting for Malkin to give the puck away for a 5-on-3, but he instead whipped a cross-ice pass to Hornqvist, who made no mistake at 8:40.

Pittsburgh stayed on the power play with Weber now in the box, and Zucker made it 2-1 just 59 seconds later when Bryan Rust delivered a sneaky feed in the slot for the winger to rip a shot upstairs.

Notes: Pittsburgh C Jared McCann sat out in favor of Sam Lafferty.
