The Chicago Blackhawks were struggling. Nikolai Khabibulin was yanked in the second period, and the Ottawa Senators looked ready to put away a big road win. Then Corey Crawford came in, and Jonathan Toews took off. Toews had three goals and an assist, Crawford made 14 saves in relief of an ineffective Khabibulin and the Blackhawks rallied for a 6-5 victory over the Senators on Tuesday night.
