Bernard Hopkins broke his own record by again becoming the oldest man to win a world title after beating Tavoris Cloud on points to claim the IBF light-heavyweight crown.
Hopkins (53-6-2, 32KO wins) benefited when Cloud was cut over his left eye in the sixth round, which the referee ruled an accidental clash of heads but replays showed the gnarled veteran opening up the wound with a left hook.
The 48-year-old, who has been linked with a bout against Wales' Nathan Cleverly, took control against his fellow American thereafter and was victorious by scores of 117-111, 116-112, 116-112 to the delight of fans in the Barclays Center, New York.
The former undisputed middleweight champion first became the oldest boxer to hold a portion of the world title when he defeated Canada's Jean Pascal for the WBC light-heavyweight championship in May 2011.
He was comfortably beaten by Chad Dawson in April last year - leading many to speculate his retirement - but his latest victory has once more galvanised his career.
