After flooring Dib with a counter left hook in the second, another left hook in the third saw the Australian shaken but able to stay on his feet.
The 33-year-old had originally been slated to fight on Khan's undercard, but after the British star's original opponent suffered a auto accident, Dib stood in as a replacement.

Khan said: "We want the Manny Pacquiao fight". The fight was pretty much one sided in Khan's favor and in the fourth round, Khan unleashed a flurry of fast punches that sent Dib down to the canvas.
In his post-fight interview, Khan said: "I felt very comfortable in there".
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.
Khan arrived in Saudi Arabia on a mission to make a massive statement in his Middle East debut which would lure the eight-time world champion Pacquiao into a fight with him in the desert.More news: National Football League suspends Jets’ Chris Herndon four games
"Hopefully, we come back again at the end of the year and bring Pacquiao here".
"I slowed myself down a little bit instead of rushing all the time", he explained. "I'm sure once they see it and feel the excitement, it will give them a big appetite for it so they can't wait to see the next show", he added. Let's hope he comes to Saudi Arabia.
