Bernard Hopkins, the oldest champion in boxing history, is set to make a historic title defense at age 47 in a rematch against fellow American Chad Dawson on April 28 at Atlantic City.

Hopkins will defend his World Boxing Council light-heavyweight crown against Dawson in a rematch of a fight last October in Los Angeles that ended in round two when Dawson lifted Hopkins by the leg and slammed him into the canvas.

Hopkins suffered a dislocated joint connecting his left shoulder and collarbone and has yet to resume full training.
