In a battle of former two-time champions, Amir Khan (34-5, 21 KOs) dropped Billy Dib (45-6, 26 KOs) twice to stop him in the fourth round.
Khan floored Dib in the second round with a fierce left hook at King Abdullah Sports City in Jeddah. A few more back-to-back punches in the third and a double left hook from the British-Pakistani boxer in the fourth forced Dib back down to the canvas, prompting a fourth-round stoppage.
Dib hit the deck once again before his corner decided it woild be best to throw in the towel.
"It's a very exciting time for boxing in the Middle East and myself and my partner Bill Dosanjh are pioneering the move with our Super Boxing League in the region", said Khan.
The 32-year-old from Bolton was back in the ring for the first time since his controversial WBO welterweight title defeat to Terence Crawford in April. "I was seeing everything, making sure I was putting in the right shots".
Billy, who got the fight last month after Indian boxer Neeraj Goyat was forced to withdraw following a vehicle crash, said, "What went wrong is that he looked bigger than what he seemed at the weighing in".
Khan came out strong and fast, utilising the hand speed we're so accustomed to seeing throughout the years.
Having disposed of the Australian, Khan told TalkSport, "We want the Manny Pacquiao fight, let's hope he comes to Saudi Arabia".
During the post-fight interview Khan said he would love to return to Saudi Arabia with a big fight against Pacquiao. Pacquiao, 40, fights American Keith Thurman for the WBA world welterweight title in Las Vegas on 20 July.
