In his last four games, he has a 4.58 GAA and .816 save percentage.
"It's not the end of the universe," Bryzgalov, 31, said of being benched.
Bobrovsky, 23, has been on a hot streak. In his last eight games, he is 5-1 with two no-decisions and a 1.55 goals-against average and .947 save percentage.
While saying they still have confidence in Bryzgalov, virtually everyone in the Flyers' locker room seemed pleased Bobrovsky was getting the nod.
"Bryz has maybe had a tough couple games, but Bob has been pretty steady the whole year," high-scoring winger Scott Hartnell said. "I think it might be good for Bryz to get a wake-up call and work on some things and get back to the goalie he can be and that we all know. That's why [general manager Paul Holmgren] signed him. He's going to be good for us. I have a lot of faith in him. He's a good man and a great goalie, and he'll be there for us."
But not on Monday - in the biggest stage of the NHL's regular season.
"It's totally deserved," center Danny Briere said of Bobrovsky getting the start. "For us, it doesn't matter who's playing, but it's good to see Bob being rewarded for his play."
"Obviously, Bob deserves it," center Claude Giroux said. "He's been playing well and since the start of the season he's been working hard. I think guys see how hard he works."
No one outworks Bobrovsky, defenseman Braydon Coburn said.
"This guy probably is the last guy to leave from the practice rink every day. I know, because I'm usually the second-to-last," Coburn said. "He's kind of a little bit of an opposite to Bryz. He's easygoing, and Bryz is a personality."
Bobrovsky refused to say he was starting, smiling and saying it was not his place to make an announcement.
