"He's doing better," said Head Coach Claude Julien. "Obviously, you didn't see him on the ice today, so we're going to shut him off for a bit and give him another day's rest at least and still continue to go day-by-day."
Julien was asked if he was at all worried about Rask's situation.
"No," he replied.
Rask is 3-0-0 to start the season with a 1.68 goals-against average and .947 save percentage. Khudobin has suited up in one game - a 4-1 loss in Toronto a week ago that he'll be looking to bounce back from. Rask missed that game due to the same soreness that will keep him out of Saturday night's action.
"We just need a strong performance from him," Julien said of Khudobin. "I think when you look at putting your goaltender in, you want him to give you a chance to win, and that's all you can ask from your goaltender."
"It's going to be a fun game, definitely," said Khudobin. "My first start at TD Garden in a long time and I'm really excited about it. I'm looking forward to it."
The last time Khudobin started a regular season game at TD Garden was on April 17, 2013, against the Buffalo Sabres.
"[The Canadiens] are really fast and move the puck really well, so it's going to be a fun game," said Khudobin. "I've been here before, so I've known this rivalry. It's always hard, it's always interesting, it's always tough games - for the fans and for us, too."
Torey Krug and the Bruins are looking to have a strong showing in front of Khudobin as well.
"He's a great goaltender," said Krug. "I think he brings certain strengths to the ice and I think he plays the puck pretty well, so we've got to make sure we're always communicating and going back on pucks fast to make sure we help him out, and he'll do the job for us."
"We kind of left him out to dry in Toronto and I know he wants to respond with a good start tonight, and the D corps wants to help him out with that."
