There’s a new boxing match about to take place between Manny Pacquiao and his handlers and fans who paid to see him fight Floyd Mayweather last weekend.

“Class-action lawsuits continue to pile up for Manny Pacquiao and his promoters for failing to disclose his injury before consumers purchased tickets and pay-per-view telecasts for his fight against Floyd Mayweather,” reports Darren Rovell, a business reporter for ESPN.com.

There are lawsuits filed in Las Vegas, Texas, Illinois and two in California. One of the California lawsuits was filed on behalf of a fan who paid $99.95 for a pay-per-view telecast. That suit says that “Pacquiao’s failure to disclose his shoulder injury turned the Fight of the Century into the ‘Sleight Of The Century,’ ” Rovell writes.

At the center of the suits, which name a number of companies and individuals, including Pacquiao’s promoter, Bob Arum, are fans who said they wouldn’t have paid to see the fight if they had known about the injury.

The class-action suit filed in Las Vegas alleges fraud and conspiracy, putting a $5 million price tag on the nondisclosure.

ESPN’s story shows a form on which Pacquiao checked the “no” box on this question: “Have you had any injury to your shoulders, elbows or hands that needed evaluation or examination?” But trainers admitted that the boxer had injured his shoulder in training and was getting treatment.

“The people who paid $99.95 to watch at home had no clue. Neither did those spending $40,000 or more for a ringside seat Saturday night in Las Vegas,” wrote Associated Press sports columnist Tim Dahlberg. ‘They all thought they were getting the Fight of the Century. Two fighters who, if not in their prime, were at least in peak condition for the fight of their lives. What they got instead was a one-armed Pacquiao chasing Mayweather around the ring for 12 rounds.”

Mayweather defeated Pacquiao in a unanimous decision. They both walked away with millions. ESPN’s Rovell reports that Mayweather received $100 million and Pacquiao $50 million. But with about $387 million in arena ticket sales, closed-circuit sales and pay-per-view money, it was estimated that Mayweather will get $180 million and Pacquiao about $120 million.

Ask for More

I was scared, but I did it. I asked for more money when I was offered my first full-time newspaper job. And I got it when starting at the Baltimore Evening Sun.

But it turns out that an overwhelming majority of new graduates don’t negotiate the salary for their first job out of college, according to Nerd Wallet, a personal finance Web site, and Looksharp, a job site targeting new graduates.

It’s okay to ask for more, reports The Washington Post’s Jonnelle Marte, who writes that the majority of companies surveyed — 84 percent — said entry-level candidates wouldn’t risk losing their job offers if they negotiated on salary. Most of the new hires who asked got a bump in their offers.

“The mismatch isn’t unique to millennials,” Marte writes. “Other studies show that most people at all ages and experience levels who ask for raises get them. The main issue is that most people don’t ask.”

And don’t believe a final offer is always final.

“Some employers might head off the conversation by saying the offer is non-negotiable, but that’s rare,” Marte says. “Three-fourths of the 700 companies surveyed by NerdWallet said they had room to increase salaries by between 5 and 10 percent during negotiations for entry-level positions.”
