Buffalo coach Ted Nolan criticized Rinaldo.
"Those are the type of hits that we have to get rid of," he said. "Those are not only dangerous hits but you're also putting a fellow player in jeopardy of his career . . . You're dealing with the brain."
"Teams need energy players like that," said Sabres defenseman Mike Weber, whom Rinaldo tripped during the game, "but there's a certain line you can't cross, and it seems like he's crossing it two, three times a year."
Flyers coach Craig Berube has praised Rinaldo for being more disciplined lately, and he even promoted him to the third line.
Rinaldo scored his first goal since Jan. 8, but he also finished with four penalties - goalie interference, charging, tripping, and a match penalty for the hit to the head.
"Got to be better. Got to be smarter," Berube said.
If Rinaldo is suspended, Steve Downie or Tye McGinn figures to play Tuesday in Florida.
Flyers center Sean Couturier drastically trimmed his "mountain man" beard, saying it was "time to move on and try to start a new streak here."
Joked Couturier, 21: "I do feel younger."
Couturier entered Sunday with one goal in his last 23 games.
Luke Schenn had 10 hits and four blocked shots. . . . Vinny Lecavalier started the night on the fourth line, and Michael Raffl centered the second unit, with Brayden Schenn moving to wing. . . . Buffalo's Ville Leino, a former Flyer, is without a goal in 56 games this season.
