The biggest name in boxing is retiring this week.

“Iron” Mike Tyson will go toe-to-toe with YouTuber-turned-boxer Jake Paul in Arlington.

The lead-up to the main event started Tuesday in Irving.

Hundreds lined up outside the Toyota Music Factory Tuesday afternoon for open workouts, including members of the Los Gallos Boxing Club, one of the oldest boxing clubs in Dallas.

“As a little kid I grew up with Jake Paul watching his YouTube videos and my dad always told me who Mike Tyson is, I really want to watch them. It’s a really cool privilege to come and watch,” said Nicholas Salinas, member of the Los Gallos Boxing Club.

“It’s not really about us adults, it’s about the kids. They are more excited. They talk about it all week,” said Javier Armenta, coach of Los Gallos Boxing Club.

Inside, boxers from the seven fights scheduled for Friday, including Jake Paul and Mike Tyson, showed off their speed in the ring.

Paul, 27, promised fans that Friday will be an early night for Tyson.

The fight is scheduled for 7 p.m. at AT&T Stadium in Arlington.

The Arlington Convention and Visitors Bureau estimates the event will draw about 50,000 visitors to the city, down from about 75,000 expected when the fight was originally scheduled for this summer.

The July bout had to be postponed after Tyson suffered a flare-up of a stomach ulcer that landed him in the hospital. He recovered quickly, but was forced to slow down his training.

At Toyota Music Factory, the 58-year-old stepped into the ring in front of a roaring crowd. He went through some of his signature moves and then showed his softer side when he talked about his son who was there and expected to attend Friday’s fight.

“Family is everything, but to my children I am nothing. But on Friday they will discover that I am very special,” said Tyson.

After his workout, Tyson stopped to sign gloves and caps for members of the Los Gallos Boxing Club.

After getting Tyson’s autograph, a young fan told NBC 5, “I feel great.” I’ve been waiting for this all my life!”
