WILMINGTON, Mass. — Bruins head coach Claude Julien confirmed that defenseman Johnny Boychuk is dealing with concussion symptoms and is being treated on a day-to-day basis.

That probably rules out Boychuk’s availability for Tuesday night’s home game with Ottawa and might also cause him to miss games with New Jersey and the New York Islanders later in the week.

Boychuk was rocked by a Chris Neil hit Saturday night early in the third period of a win over the Senators. The defenseman did not return.

Julien also said that Shawn Thornton is day-to-day and a “question mark” for the Sens rematch.
