Chris Kelly suffers fractured femur after gruesome on-ice fall (Video)

Boston Bruins forward Chris Kelly appeared to suffer some kind of left leg in injury early in the first period in a game against the Dallas Stars on Tuesday.

Kelly, a Boston alternate captain, seemed to lose balance going for a puck and his leg slipped out from under him. Above is the video.

Following the injury, Kelly was down for several minutes before being helped off the ice.

Hulking 6-foot-9 Bruins captain Zdeno Chara was part of the crew that helped Kelly to the bench.

The 34-year-old winger had two goals in 10 games this season, coming off a year where he notched 28 points in 80 games. Kelly is in the final season of a four-year $12 million contract. CSN New England's Joe Haggerty notes losing a leadership type player like Kelly would be rough for the Bruins locker room.

Update: The Bruins announced an injury prognosis on Kelly -- a left femur fracture. He's scheduled to undergo surgery Wednesday and is expected to miss the nexit six-to-eight months.
