Probable lines: Bruins vs. Leafs

Patrice Bergeron was the big name missing from practice yesterday, but he's not the big one missing this morning in Toronto.

From Fluto:

Let's see: Bergeron...check. Stafford...check. Hayes on the first line...ch- hey wait a minute.

Yes, that's David Backes missing from the morning skate, and he's thrown a wrench into the lines.

Per Mike Loftus of the Patriot Ledger, this is a weird development:

Backes did take that tumble into the boards last week, but played after. It's possible that concussion symptoms appeared late, or that something was aggravated against Edmonton.

Either way, weird stuff. The defense pairs are the same, and expect Tuukka Rask to start.
