Nico Ali Walsh, grandson of the legendary Muhammad Ali, continued his fairytale start in professional boxing by winning his second fight with a third-round knock-out of James Westley II.

Ali Walsh grabbed global headlines after beating Jordan Weeks on his professional debut in August with a first-round technical knock-out.

The 21-year-old continued following in his grandfather's huge footsteps by dropping Westley on Saturday night in Atlanta.

Middleweight fighter Ali Walsh is the son of Robert Walsh and Rasheda Ali Walsh, Muhammad Ali's daughter. He signed a deal with Bob Arum's Top Rank Boxing in June ahead of his first professional fight in the U.S state of Oklahoma.

Given his debut, the crowd were expecting big things from Ali Walsh and he did not disappoint. 

While the fight only lasted three rounds, Westley became the first professional fighter to test Ali Walsh's chin with a hefty blow. But Ali Walsh was undeterred and continued attacking Westley with his cracking right hand. 

'I know the crowd got excited seeing him hit me with a punch but I truly didn't feel it,' said Ali Walsh after the fight. 

The fighter with the famous name made devastating use of his straight right hand, quickly putting Westley on the canvas in the second round. 

Smelling blood, Ali Walsh kept the pressure on in the third round and eventually put Westley down again onto one knee using his straight right.  Westley's corner had seen enough and threw in the towel to give Ali Walsh another commanding win. 

'I'm blessed that I am following the legacy of my grandfather. Everyone who loved my grandfather is now watching me,' Ali Walsh said, before acknowledging he has room for improvement. 

'I'm happy this fight went the way I did. There is stuff I need to work on.'
