With more than 41,000 boxing fans filling Barclays Center and Madison Square Garden over two recent weekends, you might think boxing is back in New York. But that’s far from the truth.

The grassroots club shows that serve as the developmental ground for boxing prospects continue to be crippled by the insurance requirements that were included in the 2016 bill passed by the New York Legislature to legalize MMA.

The new requirements took effect last September. There hadn’t been a club show in New York since last August until Friday night, when Star Boxing promoter Joe DeGuardia revived his Rockin’ Fights series at the Paramount in Huntington, N.Y. Anthony Karperis of Hicksville retained his New York State welterweight title with a fourth-round TKO of Scott Burrell of Brooklyn in a 10-round main event.

DeGuardia limited the show to five bouts because of the new state law that requires promoters of combat sports to carry an additional $1 million of insurance on each fighter in case of a traumatic brain injury. DeGuardia said his costs are now “six times” what they were, but felt it necessary to keep his fighters active, engage his venue and encourage discussion that the insurance requirements need to be changed.

“In my view, we have to keep the attention on it,” DeGuardia said. “So I pulled up the boot straps and rolled up my sleeves and made it happen one way or the other.”

The “Rockin’ Fights” series has been a staple at the Paramount in recent years, offering a developmental ground for fighters such as former junior welterweight champion Chris Algieri and current light heavyweight contender Joe Smith Jr. Before the new law went into effect, DeGuardia had shows booked for last September and October and another planned for last November. But the new law brought an abrupt end to boxing in New York for the remainder of 2016.

DeGuardia said he likely would have promoted at least six or seven shows since August under the old requirements, and is unsure when his next promotion on Long Island will be.

“We’ve become back-loaded on some fighters because we haven’t had the same activity,” DeGuardia said.

There have been three boxing shows in New York City in 2017. Keith Thurman outpointed Danny Garcia in a welterweight unification bout at Barclays Center on March 4 that drew 16,533 fans and was shown on CBS in prime time. Gennady Golovkin retained his middleweight titles with a close decision over Danny Jacobs on March 18 before 19,939 at the Garden. That bout was seen on pay-per-view and will be replayed Saturday night on HBO.

Also, Irishman Michael Conlan made his pro debut on March 17 before 5,104 at the Garden Theater. That bout was seen on Spanish-language television in the United States and also in the United Kingdom and Ireland. Former welterweight champions Andre Berto and Shawn Porter are scheduled to meet April 22 at Barclays Center in a bout to be televised on Showtime.

DeGuardia’s concern is, major televised bouts such as Thurman-Garcia, Golovkin-Jacobs and Porter-Berto are the result of fighters who have been developed at the grassroots level. That’s no longer taking place in New York.

DeGuardia has been meeting with lobbyists and insurance experts to prepare to make a presentation to the State Legislature in hopes of getting the law amended.

“It’s a multi-tier approach to come up with solutions for everybody,” he said. “Not only does it negatively affect my business, but it also affects the boxers and their families and the fans and the vendors and restaurants in and around the venue. And New York is suffering because it’s easier to go to another state and do a show.”
