BOSTON — There was nothing out of the ordinary at the Bruins’ morning skate today except for the absence of Nathan Horton’s ever-present smile.

The Bruins, of course, will be without the forward’s services due to a severe concussion starting with tonight’s Game 4 of the Stanley Cup Final at the TD Garden against Vancouver.

Mark Recchi took the option not skate as he’s done more often than not, while rookie Jordan Caron took the morning skate in an effort to stay sharp in case more injury befalls the Bruins. Head coach Claude Julien said after the skate that Caron would also skate in the warm-up tonight.
