A month ago, the biggest question surrounding Floyd Mayweather’s schedule was whether he could physically fit three major events into four months. Now there is a growing chance that all three events will never come true.

When World Boxing News analyzed Mayweather’s reported plans in May, the concern was timely.

Mike Tyson was already struggling with a hand injury, which postponed the proposed exhibition to the fall. Pacquiao was still waiting for an official announcement, even though Mayweather claimed the deal should be completed within days.

Meanwhile, the summer exhibition with Greek kickboxing star Mike Zambidis was quick approaching.

The schedule seemed ambitious, but has since become much more complicated.

First, Zambidis

The most immediate concern is the Mayweather v. Zambidis exhibition on June 27 in Athens.

The undefeated boxing legend is currently embroiled in multiple legal battles, including a lawsuit filed by CSI Entertainment over Tyson and Pacquiao’s proposed events and a separate $175 million lawsuit Mayweather filed against former associates.

Mayweather also publicly responded to the theft allegations in Nevada, dismissing the headlines as “free promotion.”

None of these issues stopped the event in Athens.

However, if any legal changes affect Mayweather’s ability to travel abroad, the Zambidis exhibition will become the first casualty.

With only a few days left until the fight, he’s at the front of the line.

Pacquiao is still waiting

The proposed rematch with Pacquiao raised eyebrows even before the latest headlines appeared.

Mayweather stated in May that the fight should be finalized within days after plans for the Sphere in Las Vegas collapsed.

Weeks later, there is still no official date, location, press tour or promotional event.

The longer this goes on, the harder it is to imagine a fight of this magnitude taking place in the original time frame.

Vital events don’t usually happen overnight. At this point, Pacquiao remains a talking point rather than a confirmed fight.

Tyson’s problem

Then there’s Tyson. The former heavyweight champion suffered a hand injury, which delayed plans and pushed the exhibition to the fall.

Even before this defeat, Mayweather never seemed fully committed to promoting the event.

Reports continued to surface linking the pair to Africa and various dates, but Mayweather rarely spoke about the fight publicly.

Tyson’s injury created one obstacle, while the CSI lawsuit created another.

All in all, Tyson’s exhibition currently looks like the least certain of the three events.

A month ago, the challenge was to put Zambidis, Pacquiao and Tyson in the same four-month window.

The calendar remains full.

Whether all three events survive long enough to get to them becomes a completely different question.

A key factor in the fight was Schmeling’s preparation. Before the fight, Schmeling spent a lot of time studying Louis’ film. He later said he noticed that Louis often lowered his left hand after stabbing.

Schmeling noticed that Louis had a habit of lowering his left hand after throwing a jab, leaving him vulnerable to counterattacks with his right hand.

Convinced he had found the answer to the undefeated challenger, Schmeling repeatedly said he knew how to beat Louis. Louis, however, entered the fight as a clear favorite.

The plan became obvious after the opening bell.

Using his jab to control distance, Schmeling repeatedly landed a right hand over Louis’ dropped left hand in the early rounds. Louis was successful in spots, but Schmeling continued to find openings with the same counter right hand.

The turning point in the fight came in the fourth round when Schmeling connected with a right hand to Louis’ jaw, knocking him down for the first time in his professional career. Although Louis got up and continued fighting, Schmeling continued to find success with right hands as the fight progressed.

Schmeling maintained his discipline in the middle rounds, gaining the upper hand while continuing to counterattack with his right hand. In round 12 he landed a right to the body and then another right to the jaw that sent Louis near his corner. Referee Arthur Donovan counted Louis out at 2:29 of the round.

This result brought Louis the first defeat in his professional career. The fight also had political significance in the years leading up to World War II, and Nazi Germany later used Schmeling’s victory for propaganda purposes.

Louis rebounded from the defeat by winning the heavyweight championship in 1937. He later avenged the defeat on June 22, 1938, stopping Schmeling in the first round of a rematch at Yankee Stadium.

At 23 years elderly, Hackett (12-1, 9 KO) will gain significant experience against one of the most battle-hardened veterans in the sport. The Washington native has won three straight fights since suffering the only defeat of his career in December 2024 – a 10-round split decision to Jose Roman Vazquez.

The fight also marks a move up to middleweight for Hackett, who has spent most of his career at junior middleweight.

Derevyanchenko (16-6, 11 KO), now 40, remains a respected name despite defeats in two of his last four fights dating back to 2023. The Ukrainian veteran shared the ring with some of the best fighters of his era, including Gennadiy Golovkin, Daniel Jacobs, Jermall Charlo, Carlos Adames and Jaime Munguia.

Initial reports of the bout surfaced around June 10-11, when Ring Magazine reported that the fight would be added to the Zuffa Boxing card. Other media outlets soon followed, describing the contest as agreed in principle but not yet finalized.

Now it has been officially confirmed that Hackett will have the opportunity to achieve the most recognizable victory of his career against veterans who have competed at the world level for years. A victory would solidify his status as one of boxing’s rising prospects while giving him a notable name on his resume.
