He might not get to display his more mature and experienced talents in the NHL during his current stint in Boston, but back-up goaltender Tuukka Rask is still enjoying his time serving as Tim Thomas’ support while Manny Fernandez misses time with “general soreness.”

“It’s fun, of course. This is the place you want to be,” Rask said yesterday at TD Banknorth Garden in Boston. “I see the chance to come here and try to take advantage.”

This season was supposed to be all about Rask spending the entire year in the AHL, getting used to the heavy workload and smoothing out any rough spots in his game. Last season, his first in North America, included four NHL games in addition to his 45 regular-season AHL games with Providence. Now he has yet to play for Boston so far, but those NHL practices can be just as helpful — a chance, if you will, to gauge one’s skills against the top shooters in the world.

“It’s probably not as big of a deal as it was last year, the first time I got called up. But it’s always fun to come up here and challenge yourself and kind of see what it’s all about here,” said Rask, who has compiled a 19-15-0 record with the P-Bruins.

Depending on how fast Fernandez heals, Rask might get into a game. The Bruins have a back-to-back situation Saturday and Sunday as part of their current seven-game-in-12-night stretch.
