Forward Marc Savard, the Bruins’ leading scorer, has been placed on long-term injured reserve because of a broken left foot.

The Bruins did not say when Savard suffered the injury.

The Bruins recalled forward Trent Whitfield from Providence on an emergency basis.

Savard, who has four goals and three assists, will be out four to six weeks. He has led the Bruins in scoring each of the last three years, and did not miss a game last season while amassing 25 goals and 63 assists for 88 points.

Whitfield, 32, was signed as a free agent in July and has appeared in 177 NHL games with the Capitals, Rangers and Blues. He had three goals and eight assists in six games for Providence this season.
