NFL legend Tony Siragusa has died at 55 years old, his former Baltimore Ravens teammate, Jamal Lewis, confirmed to TMZ Sports. "It's a sad day to be a Raven I must say," the ex-running back said on Wednesday. A cause of death for the former defensive lineman has not yet been revealed. Siragusa -- a 6-foot-3, 340-pound defensive tackle -- initially broke into the NFL with the Indianapolis Colts as an undrafted free agent in 1990 and became a full-time starter by the 1992 season.
