The team announced Miller suffered a concussion after being hit by Milan Lucic during the Sabres' 6-2 loss to the Boston Bruins at TD Garden on Saturday. Miller was removed from the game after the second period.
On Sunday, Sabres general manager Darcy Regier told The Buffalo News that he hopes Lucic is suspended for the hit.
"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 told the paper. "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."
Miller, who was highly critical of Lucic after the game, will be replaced in the lineup by Drew MacIntyre after the latter was recalled by AHL Rochester. MacIntyre will back up Jhonas Enroth on Monday night, when the Sabres visit Montreal.
In 11 appearances this season, Miller is 5-6-0 with a 2.86 goals-against average and .909 save percentage.
