Flyers center Danny Briere, his frustration growing, made highly critical remarks Tuesday about how Gary Bettman is handling the NHL’s negotiations with the players’ union.

Multiple reports on Monday said Bettman, the NHL commissioner, suggested the league would cancel the Jan. 1 Winter Classic in mid-November if a new collective-bargaining agreement wasn’t in place by then.

“Mid-November is what, a month and a half away?” Briere bristled after taking part in an informal Flyers practice in Voorhees on Tuesday. “Maybe if he spent less time worrying about who has the upper hand and maybe more time negotiating with the players, maybe more things would get done.”
