Bruins coach Claude Julien could not say what that meant for Boychuk's return.
‘‘It’s a day-by-day situation,’’ said Julien. ‘‘We saw what happened to [Nathan Horton].
‘‘He has concussion symptoms. I don’t know if it’s been termed a concussion, but I don’t think it matters because we’re treating it as if it is. We take a cautious approach to these kinds of things and we don’t want to lose him for a long time.’’
