Kelly appeared to fall awkwardly to the ice during an attempt to steal the puck away from Stars forward Colton Sceviour, and had to be helped off the ice.
“Chris sustained a left femur fracture…and was transported to Mass General Hospital,” Bruins general manager Don Sweeney said in a press release. “He will undergo surgery on Wednesday, Nov. 4 at Mass General Hospital and his expected recovery time is between six and eight months.”
The 34-year-old will be missed by the Bruins, especially when it comes to special teams. Kelly plays the second-most short-handed minutes, behind Patrice Bergeron.
Kelly has two goals in 10 games with the Bruins this season.
