Fucale has enjoyed a strong start between the pipes for Sylvain Lefebvre's squad, boasting a 4-1-0 record in five appearances so far this season.
"I've had a good start, but there are always things to improve. As a group, we're coming along," said Fucale, who hasn't yet seen game action in the NHL ranks. "I'm taking [being called up] as a positive, and it's a good opportunity for me again."
The Sabres, meanwhile, arrived in Montreal after dropping a 4-1 decision to the Florida Panthers on Friday night in Western New York.
Paul Byron doesn't expect fatigue to be a factor for Buffalo, though.
"I expect a hard-fought game. They play a really hard game and they've got skill, so they're a pretty dangerous team," explained Byron. "I think they can beat anybody on any given night. If you're not ready, they'll make you pay, for sure."
