Ryan Miller Out Indefinitely After Suffering Concussion in Loss to BruinsRyan Miller exited Saturday's game against the Bruins after two periods. He'll now miss some more time, as ESPN.com reports that the Buffalo goaltender has suffered a concussion and is out indefinitely.

Sabres general manager Darcy Reiger confirmed the news via text message Sunday evening, according to ESPN.com's Pierre LeBrun.

Miller collided with Bruins winger Milan Lucic in the second period of Saturday's game, which sent Miller crashing to the ice violently. He would stay in the game, stopping 19 of the 22 shots he faced, but was eventually pulled following the second period.

Miller stuck around after the game and called Lucic "gutless" and "a piece of [expletive]." Lucic is reportedly scheduled to have a hearing with NHL disciplinarian Brendan Shanahan at 1 p.m. on Monday to review whether further disciplinary action will be taken against the B's forward.

It's unclear how long Miller will be out, but the Sabres have called up goaltender Drew MacIntyre from the AHL. Reiger said he hopes that Miller's injury isn't severe, but he told the Buffalo News that he thinks Lucic's hit warrants a suspension from the league.

"If this hit and other types of hits like this are not suspended, we are opening up the possibility of losing goaltenders to injury," Regier said sternly, the Buffalo News reports. "And not just injury, but concussion. … When I look at the position of goaltending, in a lot of ways it's not unlike quarterback in football. I feel very strongly the protection has to be provided and players committing these types of action should be punished.

"The last thing we need to do in the NHL is to be losing our stars to concussions on plays like this."
