Amir Khan has secured a knockout victory over Billy Dib in Saudi Arabia.
Dib, who previously spent most of his career operating at super-featherweight, moved up three weights to take on Khan in Jeddah, after original opponent Neeraj Goyat was ruled after he was injured in a car accident.
The Australian was unable to live with Khan superior hand speed and strength, however, with the Briton sealing a comfortable victory in the fourth round.
Khan floored Dib in the second round with a superb left hook, with former featherweight champion missing wildly in his attempts to level a contest that was one-sided from the opening bell.
A flurry of shuddering body shots in the fourthdropped the 33-year-old again, prompting his team to throw the towel in with Khan extending his professional record to 34 wins with five defeats.
Khan was fighting for the first time since his defeat to WBO welterweight champion Terence Crawford in New York in April.
