There's also speculation that Pacquiao, 60-7-2, 39 KOs, would fight his old rival Floyd Mayweather again soon after the two met again at an National Basketball Association game at the Staples Centre on Tuesday.
Pacquio leant down to Mayweather, who stayed seated, and shook the undefeated American's hand before moving on.
But no concrete plans have been announced regarding a rematch. One thing Pacquiao wasn't interested in doing was discussing future fights, particularly a potential rematch against Floyd Mayweather.
Floyd Mayweather Jnr made another weird return to the ring on New Year's Eve when dismantling Japanese kickboxing sensation Tenshin Nasukawa inside a round of what was billed as an exhibition match. "But right now my focus is this fight because I'm not taking Adrien Broner lightly or underestimating Broner".
Manny Pacquiao turned 40 years old.
Trainer Ken Cunningham declared: "I've never seen Adrien this focused and I've been around him for years".
"I'm just ready to go out there and prove the naysayers wrong", he said. It is not accurate simply to say that a much older fighter will lose against a younger one.
Broner, an experienced and talented former four-division world champion himself, says he is as focused as hes ever been.
Ray Mancini - Broner can fight.
For Pacquiao it would be his chance to redeem himself for a 2015 unanimous decision loss to Mayweather, and for Broner it would be the chance to validate his skills against the MI born fighter, who has acted as a mentor to Broner.
After Pacquiao got off the call, Adrien Broner got on and took questions from the press.
Pacquiao has fought professionally 69 times and his record stands at 60-7-2. Though Pacquiao told the Times the thinking in his heart is "that there will be [another] fight", he seemed resigned to Mayweather being retired in Tuesday's episode of Inside PBC Boxing on FS1.
Leo Santa Cruz - If Broner will train harder and be 100% prepared, he could beat Manny Pacquiao. "A win here and I'm a legend overnight". When asked if he would implement a similar schedule next week in Las Vegas now that he's back in the fold, Roach said he hasn't thought that far ahead.
Michael Rapaport - I think Broner's best days are behind him. "I just don't let it get to me". The event is produced and distributed by SHOWTIME PPV® from MGM Grand Garden Arena in Las Vegas. Although big name fighters like Vladimir Klitsko, Bernard Hopkins and Roy Jones successfully fought over the age of 40, they are the exception. Manny Pacquiao kind of refuses to do that.
Fernandez said the emphasis is to pounce on Broner's flat-footed stance and eventually take him out with a punch or punches similar to what Pacquiao unleashed on him to culminate Thursday's workout.
