Kimmo Timonen used a back exit to sneak out of the Flyers’ dressing room late Thursday night, yet still was noticed by reporters. The 38-year-old defenseman was easy to spot in an outside hallway. He was the one walking with a bad limp. It was another typical work day for the Flyers, who lost another player and won another game in continuing their against-all-odds playoff push, this 5-3 victory over the Toronto Maple Leafs stretching their season-long win streak to four games. The night before, the Flyers rallied in the third period for a home win over Montreal and lost tough-guy winger Zac Rinaldo indefinitely to a high ankle sprain. On Easter Sunday, forward Max Talbot broke a leg early into a game in which the Flyers were down two goals in the third period before beating Washington in overtime. Last week it was more of the same with three key defensemen dropping — Andrej Meszaros and Braydon Coburn for the season with shoulder injuries, and Nick Grossmann with a lower-body issue that still is bothersome enough that he didn’t travel with the Flyers for the first two legs of this Toronto-to-Winnipeg-to-Long Island road trip.
