It's do or die for four division world champion Adrien Broner (33-3, 24 KOs), when he faces Jessie Vargas (28-2, 10 KOs) at the Barclays Center in Brooklyn, New York.
The contest takes place at a catch-weight of 144-pounds. Vargas is a replacement opponent for Omar Figueroa, who withdrew with an injury.
Vargas, a former junior welterweight and welterweight world champion, is a slight betting favorite with some of the bookmakers.
At one time Broner was considered to be one of the best fighters in the world, but his career has declined over the years.
He is coming off a clear twelve round decision loss to Mikey Garcia in July of 2017. Garcia had moved up from the lightweight division to take that fight and outworked Broner over the distance.
Broner believes that Vargas is good fighter, but a level below.
"I hope I get credit when I beat Jessie Vargas. I hope I get the credit I deserve. People want me to lose and go away, but guess what? I worked harder than ever for this fight. I'm not losing to Jessie Vargas. I'm a four-time world champion and soon to be five-time world champion this year," Broner said.
"I'm on a different level than him. I'm going to prove it on Saturday. I don't worry about any of the negativity that surrounds my name. I'm just ready to go put on a show. I'm taking over this year. It all starts with Jessie Vargas on Saturday night. I'm going to be myself, and put on a great show."
Broner, 28 years old, expects to retire as one of the best boxers of their generation - and he expects the fight with Vargas to become the start of that campaign.
"I'm still one of the best fighters of this era. When I'm done with my career, I will be one of the best to ever lace up a pair of boxing gloves. I just can't wait to give everyone something to remember on Saturday," Broner said.
"Being with Kevin Cunningham in camp changed a lot. It took a while to get used to it. This is the first camp I've done since I was kid with a new coach. There were no distractions down at camp. It was all work, no play."
