Boston have updated their roster page on the Bruins site-always a good indication of any change to who's where in the organisation.
And this time round, the defence is the focus:
You'll notice in that picture that while Adam McQuaid is back, there's no Colin Miller, which could imply he's on his way back to Providence.
Let's just say that this is probably not a change that will be greeted with open arms and joy by many in the Bruins fanbase. Colin Miller has been one of the pleasant surprises of a rollercoaster Bruins D unit this year, but with Joonas Kemppainen back up, somebody had to make way to allow McQuaid, who the Bruins rate as "questionable" to play tonight v Columbus, back onto the active 23-man roster without breaking the limit, due to Patrice Bergeron not being placed on IR.
It appears that Chiller is the odd man out. Whether that's deserved or not is another question entirely.
