Hart: Norton was the one fighter who troubled Ali

The Sun's boxing expert Colin Hart joined the Alan Brazil Sports Breakfast show to pay tribute to Ken Norton, who passed away on Thursday morning.

Hart, who covered the controversial second fight between Muhammad Ali and Norton, claims the Jacksonville born star was one of the only fighters who could trouble the 'Greatest'.

The former heavyweight champion of the world won the first bout between the pair and broke Ali's jaw during the encounter.

Norton, who had been in poor health following a series of strokes, died at a care facility in Las Vegas, Nevada.
