Buffalo goalie Ryan Miller is out indefinitely with a concussion, the Sabres said, but Boston Bruins forward Milan Lucic won't be suspended as a result of the collision between the two players.

Lucic had a hearing with National Hockey League disciplinarian Brendan Shanahan on Monday afternoon, but according to the league's website, the Bruins forward will not be suspended or fined.

The Sabres revealed the nature of Miller's injury late Sunday, while also announcing they had called up goalie Drew MacIntyre from their American Hockey League affiliate in Rochester. MacIntyre is expected to serve as backup to Jhonas Enroth on Monday night at Montreal.

At 13:12 of the first period on Saturday night, the Bruins left wing collided with Miller at the faceoff dot after the netminder played the puck to negate a breakaway by Lucic, causing his mask to fly off.

As he sat on the ice, Miller swung his stick at Lucic just before two Sabres pounced on the six-foot-three, 230-pound Bruin, who was assessed a minor penalty for charging.

Miller was replaced to start the third period by Enroth, and Sabres head coach Lindy Ruff had said following the game that Miller had a sore neck.

Miller called Lucic's actions "gutless."

Sabres general manager Darcy Regier told the Buffalo News on Sunday night that Lucic should pay a price for the hit.

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

This is the second concussion for Miller in a span of eight months. He missed four games late last season after struck in the mask by shots in back to back outings.

Miller has struggled of late, having allowed 20 goals on 148 shots in going 1-5 in his past six starts.

The Sabres didn’t come to Miller’s defence, save for a few shoves by forward Thomas Vanek and defenceman Andrej Sekera.

Tough guy Paul Gaustad, who was on the ice with Vanek, Sekera, Tyler Myers and Jason Pominville, appeared to regret not taking action.

"You could go to each one of our players and they would tell you that they wished they had dealt with it differently," Regier said. "And they will deal with it differently in the future … We were all disappointed."

Myers was scratched for the team's game Monday night in Montreal.

The Bruins and Sabres next meet Nov. 23 at Buffalo.
