Sabres goalie Ryan Miller out with concussion following hit by Lucic

BUFFALO, N.Y. - Buffalo Sabres goalie Ryan Miller is out indefinitely with a concussion after being levelled by a hit from Boston Bruins forward Milan Lucic.

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

Miller was hurt about 14 minutes into the first period of a 6-2 loss at Boston on Saturday night, when he left his crease to play the puck before being checked by Lucic, who was attempting to chase down a loose puck. Lucic received a minor penalty for charging.

Miller continued playing through the end of the second period, before being pulled after allowing three goals on 22 shots.

The 2010 Vezina Trophy-winner did not return to the bench for the third period, but made sure to stick around to provide expletive-laden post-game comments.

"(Lucic has) 50 pounds on me and he runs me like that? It's unbelievable," Miller said. "Everyone in this city sees him as a big tough solid player. I respected him for how hard he played. That was gutless."

Immediately after being hit, Miller used his stick to take a swipe at Lucic but missed.

Sabres coach Lindy Ruff said following the game that Miller had a sore neck.

This is the second concussion for Miller in a span of eight months. He missed four games late last season after being 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.
