Brayden Point scored the winning goal in overtime and forced a Game 7, as the Tampa Bay Lightning secured a thrilling 4-3 victory over the Toronto Maple Leafs on Thursday.

Ondrej Palat, Anthony Cirelli and Nikita Kucherov also scored for the reigning Stanley Cup champions, but they had to battle until 1:56 remaining in overtime for Point's sealer.

The Lightning had to fight their way back from 3-2 down in the final period with their season on the line, after Leafs captain John Tavares scored twice in the second period's closing 34 seconds.

With his side dropping a lead for the second straight game, Tavares said the focus is now on regrouping as the series heads back to Toronto for the decider.

"We worked hard all year to earn home ice and we've got a great opportunity going home in front of our fans to try to close this thing out," he said.

"So just regroup here, and look forward to the opportunity. This is what the game's all about."

The Boston Bruins also forced a Game 7 after they defeated the Carolina Hurricanes 5-2, while the St. Louis Blues advanced to the second round, beating the Minnesota Wild 5-1 in Game 6.

In Thursday's final game, the Edmonton Oilers evened their series up with the Los Angeles Kings in Game 6, winning 4-2.
