The Bruins dropped a 5-3 decision to the Penguins Tuesday before 17,535 at TD Garden. That wasn’t their primary concern.
Their worries centered around the condition of Johnny Boychuk. At 6:45 of the third period, Boychuk departed the Garden ice with his arms draped around the shoulders of Chris Kelly and Brian Rolston. Boychuk placed no weight on his left leg, which he had clanged into Pittsburgh’s Arron Asham during an awkward check. Coach Claude Julien said the collision took place on the side of Boychuk’s leg.
