The Montreal Canadiens strung together a fourth straight NHL win on Tuesday, despite the absence of star goaltender Carey Price.
Price's understudy Dustin Tokarski made 36 saves in the Canadiens' 2-1 shoot-out victory over the Florida Panthers at BB T Center as they reclaimed top spot in the Atlantic standings.
The Canadiens are level with the Tampa Bay Lightning on 50 points, having played one fewer game than their title rivals.
Brendan Gallagher's second-period goal had Montreal on track for a regulation win, before Florida's Nick Bjugstad equalised inside the final two minutes.
But PA Parenteau delivered the only goal in the shoot-out, to preserve the Canadiens' winning streak.
The Nashville Predators continue to stalk the Central-leading Chicago Blackhawks, after posting a 3-2 win over divisional rivals the St Louis Blues.
The second-placed Predators put four points between themselves and the Blues in third, with Shea Weber the star for the victors with two goals.
The Vancouver Canucks are clear second in the Pacific standings, one point above the Los Angeles Kings, after results favoured the Canadian club.
Ryan Miller made 31 saves in the Canucks' goal as they downed the San Jose Sharks 3-1, while the Kings were trumped by the Edmonton Oilers 3-2 after a shoot-out.
