The plan was for Tuukka Rask to play the entire 60 minutes, but once the Flyers opened up a 4-0 lead after two periods, Cassidy elected to have the B's starting netminder take it easy for the rest of the night.
"That was a discussion I had with our goalie coach [Bob Essensa] and Tuukka himself," said Cassidy. "When you're not playing that well and you're giving up shorthanded, tick-tack-toe goals, it might be time to say, 'Hey, you know what? We're just not there in front of the goaltender.'
"We don't want him to get into bad habits and get frustrated. He's not going in Saturday so we'll just get him some extra practice."
Despite starting just two games during the preseason, Rask feels ready to go for next week's opener against Nashville.
"We mapped it out before and talked about playing a couple Philly games and see how we feel. I felt good all along," said Rask. "It's been a good camp…long camp. I think it's time to put that behind. I know we've got one more game left, but focus on next Thursday."
