A fight between the pair has been rumoured in recent months with WBA's secondary welterweight title holder Pacquiao keen to unify WBA by beating Thurman.
Despite reports from the United States saying that Pacquiao is slated to face Keith Thurman on July 20 in Las Vegas, the Filipino fighter's camp and Al Haymon's Premier Boxing Champions (PBC) have yet to make a confirmation.
Gibbons also said veteran athletes like 41-year-old American football player Tom Brady and 43-year-old professional golfer Tiger Woods have influenced the 40-year-old Pacquiao (61-7-2 win-loss-draw record with 39 knockouts) to strive more in his professional boxing career. It was Thurman's first fight since facing Danny Garcia in 2017.
"The summer just got a little hotter", said Pacquiao as he tweeted their fight poster.
Meanwhile, Thurman ended nearly two years out of boxing the following weekend, when he clinched a unanimous decision against American compatriot Josesito Lopez to retain the "super" welterweight belt. He has faced and beaten two former welterweight champions, Robert Guerrero and Danny Garcia, and one current welterweight champion of the world, Shawn Porter.
Promoters confirmed the fight in a statement, describing it as "the biggest night of boxing this year".
Last time out, Pacquiao saw off Broner convincingly, defeating the four-division champion on points in Las Vegas.
"Manny Pacquiao is not going to be here for the years to come". "That is why I am fighting him". "I'd even fight him in the Philippines if I have to".
"He's not the young Manny Pacquiao that he once was but he still is a great, world-class fighter. It's an exciting fight and I think the fans would love it". We would love that fight.
