BOSTON Patrice Bergeron was at the Bruins' team facility at TD Garden on Tuesday morning, getting treatment and spending time with his teammates while they practiced on the ice and readied themselves for the Eastern Conference finals.Coach Claude Julien confirmed the 25-year-old assistant captain was in the building for the first time since suffering a mild concussion last weekend in Game 4 against the Philadelphia Flyers. Bergeron has been making steady progress in coming back from his third concussion in the last four years, and his presence at Bs practice is another sign that things are looking up for him even if hes still definitively out for the first couple games of the series."He's doing better, said Julien. He's dealing with the concussion symptoms and the protocol that goes along with that. He's here today because he's feeling better. We're getting somepositive feedback from him.
