Philadelphia Flyers forward Danny Briere, who was on the wrong side of a clean hit that sparked a brawl in Sunday's game against the Pittsburgh Penguins, is out indefinitely with an upper back contusion, the team announced on Monday.
Nicklas Grossmann was also injured against the Penguins and is out 7-10 days with a lower body injury.
Briere was leveled by Pittsburgh's Joe Vitale late in the third period of Philadelphia's 6-4 win on Sunday, an incident that set off a fight that had the teams' coaches screaming at each other across the boards.
Grossmann left the ice after a first-period collision and did not return.
