Boxing legend Muhammad Ali's grandson Nico Ali Walsh made a successful professional debut as he defeated Jordan Weeks by technical knockout on Saturday. Middleweight fighter Ali Walsh is the son of Robert Walsh and Rasheda Ali Walsh - Ali's daughter. After the bout, Ali Walsh celebrated with family members and later on with promoter Bob Arum. The 21-year-old had signed a deal with the 89-year-old Arum's Top Rank Boxing in June ahead of his first pro fight in Oklahoma. During the fight, Ali Walsh wore trunks made for his grandfather. He knocked Weeks down midway through the first round before the referee stopped the fight. "Obviously my grandfather, I've been thinking of him so much. I miss him. It's been an emotional journey," ESPN quoted Ali Walsh as saying. "I think me and him [Weeks] made a little bit of history tonight. This lived up completely to my expectations." Ali Walsh then paid tributes to his grandfather, "It seems like a lot of pressure; to me, it's just my grandfather," he said Ali Walsh. "He's the greatest fighter who ever lived - maybe the greatest person. I'm never wearing these trunks again."
