The Devils lost in overtime to the Sharks on Friday night and also lost center Jacob Josefson, who suffered a broken right clavicle during the first period. Josefson underwent surgery Saturday morning, according to multiple reports. He reportedly will be out three to four months. The Devils now are without their top two centers. First-line center Travis Zajac suffered a torn Achilles tendon during an offseason workout and is expected to be sidelined until December.
