The lefthanded netminder, who joined the team for its trip to The Great Wall of China on Sunday, was presented with his No. 1 Bruins sweater by team president Cam Neely and held court with a large contingent of Chinese media prior to practice.
"It is a dream come true," said Dun, "a surreal moment to step out on the ice and practice with some of the best players of the world."
Prior to his stint in the KHL, the 5-foot-11, 171-pound goaltender appeared in 16 games for the University of British Columbia, compiling a 7-4-1 record with a 2.87 goals against average and .910 save percentage. In 2014-15, Dun made four appearances for Northern Michigan University, posting a 1-0-0 record with a 2.40 goals against average and .918 save percentage.
With the likes of Brad Marchand, David Pastrnak, and Charlie McAvoy peperring him with shots during Monday's practice session, Dun quickly noticed how much the speed and intensity ratchets up at the NHL level.
"It was fast, quick," said Dun. "It's pretty much everything you would expect, some of the best players in the world out there. Got to keep sharp and be on my toes…the hockey IQ out there, the release of the shots. If you give them anything they're gonna take it. That was the biggest difference. They know where they're shooting every single time."
