TORONTO — Nazem Kadri scored 2:51 into overtime and the Toronto Maple Leafs beat the Boston Bruins 4-3 on Thursday night.

Brad Marchand, Milan Lucic and Patrice Bergeron scored for Boston, which lost back-to-back games for the first time since Feb. 26 and March 1. Boston backup goalie Chad Johnson made 27 saves.

Bergeron tied the game at 12:51 of the third against backup goalie James Reimer after Lucic scored 5:03 into the final period.

Paul Ranger, Tyler Bozak and James van Riemsdyk scored for Toronto, which lost goaltender Jonathan Bernier midway through the third.

Van Riemsdyk reached the 30-goal plateau for the first time in his NHL career. His previous career high was 21, set with the Philadelphia Flyers in 2010-11.

It remains to be seen how severe Bernier’s injury is. He left 7:22 into the third period after Ranger pushed Patrice Bergeron into him.

Reimer replaced him and stopped 10 of the 11 shots he faced.

Bernier recently missed five straight games with a groin injury sustained March 13 in Los Angeles.

Toronto (38-32-8) improved to 84 points with its second straight victory, a very important one after eight straight regulation losses sent the season off the rails. But the Leafs didn’t get any help in their playoff quest, as the Columbus Blue Jackets beat the Philadelphia Flyers to get to 85 points and remain in the Eastern Conference’s second wild-card spot.

The Blue Jackets also have two more games to play — six to the Leafs’ four.
