In yet another must-win game, this time against the division rival New York Islanders, the Flyers sure would love to have Danny Briere in the lineup tonight. He’s scored more goals (19) against the Islanders than any other team during his 15 NHL seasons. It would have been a good opportunity for him to break his current 13-game goalless drought in what has been a down year. Briere has five goals and eight assists in 26 games this year. Instead, a concussion will keep him out of a ninth consecutive game. Briere is making improvements. He skated with the team Monday for the first time since sustaining the concussion in a practice on March 23. “It’s fun to be back (practicing), but at this point I’m still not sure when I’ll be back,” Briere said. “It’s a step in the right direction.” He’s not having major headaches like he was for the first week of his recovery, but he’s still having a hard time distinguishing a normal headache from a concussion symptom. He skated as a fourth defensive pairing with Tye McGinn Monday and is hoping to be ready for Saturday’s game in Buffalo. “That would be great if everything keeps going the way it is now,” Briere said. “There’s a chance.” The 35-year-old center admits it’s more difficult to sit out when the Flyers absolutely need wins, especially against teams in front of them like the Islanders, who own the last playoff spot in the Eastern Conference.
