There’s deadlines and then there’s Floyd Mayweather Jnr time.

The two are nearing a collision course with the president of Manny Pacquiao Promotions reporting Mayweather confronts an end-of-business Tuesday finish line to commit to the Pacquiao rematch being a professional boxing match, not an exhibition.

On Monday’s “Inside The Ring,” television show, MP Promotions’ Jas Mathur said Mayweather faces the Tuesday deadline to commit to the real fight putting his perfect 50-0 record on the line after telling reporters in late March that the bout would be an exhibition and he was not sure if it would be where it is signed to occur, The Sphere in Las Vegas.

Another figure connected to the deal told BoxingScene the window is tightening for Mayweather, 49, to officially clarify his involvement after signing to participate in a legitimate prizefight September 19 on Netflix.

What will transpire Tuesday is unknown. Anyone who’s spent significant time around Mayweather knows he moves to his own schedule.

Pacquiao said on “Inside The Ring” that Mayweather is “scared” to risk his perfect record after leveraging it so many times in lucrative exhibition bouts, including one against Logan Paul.

In his late-March interview, Mayweather intimated the fact that he and Pacquiao are already Hall of Famers means they don’t need to stage a real fight that will count against their records.

But Pacquiao, coming off a July WBC welterweight title draw versus former champion Mario Barrios, yearns to avenge defeat in the richest prizefight in history, when he fought through a right shoulder injury that required surgery and lost a unanimous decision to Mayweather at MGM Grand in Las Vegas.

Pacquiao has honored his commitment, appearing at several major sporting events – baseball, hockey and soccer – while throwing out the first pitch at Yankee Stadium and meeting with several reporters, including BoxingScene, to promote the fight.

Pacquiao associate David Sisson told BoxingScene the fans’ reaction to seeing Pacquiao, 47, has been incredibly supportive this time around, as it seems he will be the wide fan favorite when the fight occurs.

First, Mayweather has to meet his deadline.

If he rejects the real fight and insists on an exhibition, Pacquiao told BoxingScene Mayweather will experience “problems” as a result of the contracts he has already signed. 

Tick, tick, tick.
