On Friday, Boston head coach Claude Julien updated the health of defenseman Johnny Boychuk, who was stretchered off the ice following a hit from Max Pacioretty in a 2-1 loss to Montreal on Thursday night.
Boychuk, 29, has one goal and six points through 27 games this year and is on pace to set a career-high in assists.
