Income tax issues reportedly led Pacquiao to take his career outside the U.S.in recent years with the Broner bout marking his first return since he outpointed Jessie Vargas in their November 2016 welterweight title bout in Las Vegas.
It was officially confirmed on Monday that the MGM Grand will be the venue when Pacquiao puts his WBA World Welterweight title on the line.
Broner, 29, considers himself the younger brother of friend and mentor Floyd Mayweather Jr. and even tries to mimic the undefeated fighters defensive shoulder roll in the ring.
After a year off, Pacquiao (60-7-2, 39 KOs), who turns 40 on December 17, returned in July and knocked out Lucas Matthysse in the seventh round - Pacquiao's first KO since his 2009 victory over Miguel Cotto to win his first welterweight title - to win a secondary welterweight belt in Kuala Lumpur, Malaysia. Broner, one of the most talented fighters in boxing, is aiming for his second stint as 147-pound champion.
When Pacquiao and Mayweather first fought on May 2, 2015, the men emerged runaway winners financially. "I missed fighting in America and I can't wait to fight here again".
Manny Pacquiao: We can't underestimate this fight.
Broner was significantly more animated on the microphone, as he addressed the fight and had some pretty interesting words for Pacquiao as well. I get more views than everybody when I fight.
"It's gonna be a hell of a fight". I'm not coming to just pick up a check. "Y'all got me f*cked up if you think I'm going to lose to Manny Pacquiao", he added.
Broner, who has won world titles at junior lightweight, lightweight, junior welterweight and welterweight, knows what a victory over Pacquiao could do for him. I know January 19 I gotta be at the top of my game.
'The things he's done in this game are unbelievable.
"I win, I turn legend overnight", he said. As long as I'm still here in boxing, it depends on him, if he comes out of his retirement. I know January 19 I gotta be at the top of my game.
Broner, from Cincinnati, is 33-3-1 with 24 knockouts. "But it would be a mistake to overlook Adrien Broner in this fight".
"Yes, of course", Pacquiao insisted. He's been knocked out; we know he can go to sleep.
Stephen Espinoza, who heads Showtime Sports, said he believes Broner is a live underdog. Adrien is a tough opponent with an accomplished record. Broner never backs down from a challenger.
