David Krejci leaves game vs Senators, not expected to return

Well, it looks like some real bad news could be coming out of Ottawa (or wherever that arena really is) tonight:

At the beginning of the third, Krejci didn't come back to the bench:

Don't see David Krejci.

You know it's bad when the Bruins official account mentions it:

No sign of David Krejci on the ice or bench with just over 6 gone in the third period.

And then the bad news:

David Krejci is not likely to return (upper body). ^BB

Looking at the shift-chart, Krejci finished out the second period, and then did not return:

Ryan Spooner has been taking Krejci's place. We'll have more info when we can find it.
