07:29 AM ET 10.22 | So far this season, the Bruins have yet to give Tuukka Rask a night off. [Rask's] new backup, Chad Johnson, has played zero games. That is a ratio that cannot last, and it may change [Wednesday] night when the Bruins face the Sabres in Buffalo. "We'll probably give him a shot there at some point, and Buffalo may be one of the games we give him," said Bruins coach Claude Julien after yesterday's lengthy practice at Ristuccia Arena. ... [The Bruins] play three games in four nights starting tomorrow, including a very rugged showdown Thursday at the Garden against the top-ranked San Jose Sharks. With the first pair of back-to-back games, the time is right for the 27-year-old Johnson's first start. "We haven't made the final decision yet, but I will put him on notice," [said Julien].
