OTTAWA - Stephen Weiss scored with 9.1 seconds left in overtime to give the Florida Panthers a 4-3 win over the Ottawa Senators on Monday night.
Weiss drove a shot from just over the blue line past Alex Auld as Florida improved to 5-1-2 in its last eight games.
Panthers goalie Craig Anderson slid across to his right to deny Mike Fisher with a sensational save moments earlier. Anderson finished with 34 saves.
Jay Bouwmeester drew Florida even for the third straight time with a power-play goal midway through the second period.
Michal Repik scored in his NHL debut earlier in the period to tie it at 2-2, and Nick Boynton drew the Panthers even at 1-1 with his third goal 11:26 into the first.
The Senators had a great opportunity to gain the lead for a fourth time late in the second, yet failed to convert on a two-man advantage that lasted the final 1:29 of the middle period.
Kelly opened the scoring when he pushed a loose puck across the goal line while Senators forward Nick Foligno fell into the net. After a video review supported the on-ice call, referee Tom Kowal announced the decision to the crowd, describing it as "a good hockey goal."
Boynton drew the Panthers even with his third goal at 11:26.
Heatley scored his team-leading 14th goal 2:32 into the second, beating Anderson with a shot from the right side.
Repik, who was called up from Rochester of the AHL earlier in the day along with forward Tanner Glass, drove the crease and put away Auld's rebound of Keith Ballard's shot from the left corner.
Repik skated straight to the Panthers' bench to celebrate the goal while Ballard recovered the milestone puck from linesman Derek Amell.
Tanner and Ottawa's Chris Neil got fighting majors one second later when they squared off after lining up for the ensuing faceoff.
Spezza, who recorded a hat trick in Saturday's 3-2 win over Pittsburgh, put Ottawa ahead 3-2 with his seventh goal in six games - his 12th of the season - at 8:20.
Ottawa defenceman Anton Volchenkov was given a boarding minor with 2:29 remaining in the third for his hit from behind on Panthers right wing Brett McLean.
