Goaltender Tuukka Rask said he's healthy enough to start for the Bruins after leaving his past start in the second period of a 5-1 loss at the Pittsburgh Penguins on Sunday. Rask had a reoccurrence of a migraine headache problem that hadn't affected him in a game for a couple years. Rask took part in an optional morning skate Tuesday. "I think there's nothing really you can do except sleep properly, and eat and drink properly," said Rask, 22-12-4 with a 2.11 GAA and .920 SV%. "I guess that's the only thing because you don't know what causes it, but my guess is that the schedule's been so busy, lack of sleep and I got a little dehydrated. So that's the best guess I can get. But nobody really knows how to prevent it or what causes it. Just try to be as rested and hydrated as possible." The Bruins, who have lost four in a row (0-3-1), held an extra video session prior to practice Monday in an effort to get back on track and improve their 10-12-0 home record. "We've got to kind of respect our game plan, execute it well and that normally helps you quite a bit," coach Claude Julien said. "Right now we were a little bit all over the place, especially last game, so that's what we addressed yesterday moving forward." The Bruins lead the Red Wings by four points in the Eastern Conference standings, but neither holds a Stanley Cup Playoffs spot. Detroit has three games in hand on Boston.
