Former NFL great Junior Seau, who played most of his career at linebacker for the Chargers, has died. He was 43. "Everyone at the Chargers is in complete shock and disbelief right now. We ask everyone to stop what they're doing and send their prayers to Junior and his family," the team said in a statement. The San Diego Union Tribune reported a 911 call came from Seau's Oceanside home at 10 a.m. local time.
