Having a flu bug work its way through the dressing room is nothing new in hockey, but yesterday’s sparsely attended Bruins practice was pretty unusual. The B’s had seven players and one coach knocked out of commission due to flu-like symptoms. Gregory Campbell, Daniel Paille, Nathan Horton, Andrew Ference, Patrice Bergeron, Anton Khudobin, Adam McQuaid and assistant coach Doug Jarvis were all excused from yesterday’s session. The B’s fly this morning to Tampa, where they’ll practice today in preparation for tomorrow night’s game against the Lightning. Coach Claude Julien said that there were no plans to make any emergency call-ups, but if that was needed, it would be done today. “We’re hoping it’s a short-term thing, which it appears to be,” Julien said. Ference, for one, tweeted yesterday that he was feeling “much better” in the afternoon. With the heavily condensed schedule in March and April, opportunities to get a good practice in like yesterday are running out, but it could have been worse. “We made the most of what we needed to do with this group that we had, and I thought it was still a good practice day,” Julien said. “If you want to look at the bright side, it’s better that it’s happening now rather than (tomorrow) morning. Hopefully we’ll have it all taken care of by (tomorrow).” Now it’s up to the rest of the players to do what they can to remain upright. “That’s quite a few guys under the weather. Just have to wash your hands a lot and stay healthy,” Jay Pandolfo said. Chris Bourque added, “You just have to keep a positive frame of mind, keep telling yourself you’re not sick, and get some vitamin C in you. Hopefully the guys are getting a lot of fluids and not getting sick.”
