Trocheck, who missed 27 games because of a fractured right ankle sustained against the Ottawa Senators on Nov. 19, assisted on defenseman Mike Matheson's goal at 14:59 of the first period that gave the Panthers a 2-1 lead. Trocheck had three shots on goal, a game-high seven hits and was plus-2 in 18:12 of ice time.
"It was awesome," Trocheck said. "Never felt better. Just thankful that I'm able to come back and play hockey again. It's been a long time coming. You never really realize how much you miss hockey until you're watching your teammates play and you're not able to."

Mike Hoffman and Frank Vatrano scored for the Panthers (18-20-8), and Roberto Luongo made 20 saves for his 480th NHL win.
Florida won for the first time since Dec. 31 to end its longest losing streak (0-5-2) since losing nine straight from Oct. 22-Nov. 10, 2013 (0-5-4).
"It was huge for our club, especially against a team like Toronto, which is one of the best in the league," Luongo said. "Starting with our last game in Montreal (5-1 loss in which the Panthers outshot the Canadiens 53-28), even though we didn't win, I thought we played the right way and we built off of that and had a 60-minute game tonight."
