Johnny Boychuk has a concussion, is out indefinitely

It comes with little surprise that Bruins defenseman Johnny Boychuk officially has been ruled out indefinitely with a concussion. Boychuk was absolutely crushed by Senators forward Chris Neil in Ottawa this past Saturday in a collision that left Neil shaken up as well. Despite the viciousness of the hit, it was a clean shoulder-to-chest impact.
Given the current sensitivity surrounding concussions in the NHL there is no timetable for Boychuk's return. We've seen how coming back too early from concussions can turn into a serious problem so I don't expect to see Boychuk suit up too soon.

Yesterday's trade deadline acquisitions of Matt Mottau and Greg Zanon have given the Bruins some extra depth at defense and we should expect too see significant ice time for one of those guys now that Boychuk has been sidelined. 
Dennis Seidenberg replaced Boychuk as Chara’s linemate in practice yesterday and the two were a formidable duo in the playoffs last year but it was Andrew Ference who was paired with Z this morning, so it will be interesting to see what lines Claude Julien puts out on the ice tonight in the latter half of the home-and-home against Ottawa.
