NEW YORK (AP) — The head coach of the Portland Trail Blazers and a player for the Miami Heat were arrested Thursday along with more than 30 other people in a takedown of two sprawling gambling operations that authorities said leaked inside information about NBA athletes and rigged poker games backed by Mafia families.

Portland coach Chauncey Billups was charged with participating in a conspiracy to fix high-stakes card games tied to La Cosa Nostra organized crime families that cheated unsuspecting gamblers out of at least $7 million. Heat guard Terry Rozier was accused in a separate scheme of exploiting private information about players to win bets on NBA games.

The two indictments unsealed in New York create a massive cloud for the NBA — which opened its season this week — and show how certain types of wagers are vulnerable to massive fraud in the growing, multibillion-dollar legal sports-betting industry. Joseph Nocella, the top federal prosecutor for the Eastern District of New York, called it “one of the most brazen sports corruption schemes since online sports betting became widely legalized in the United States.”

“My message to the defendants who’ve been rounded up today is this: Your winning streak has ended,” Nocella said. “Your luck has run out.”

Both men face money laundering and wire fraud conspiracy charges. Also charged was former Cleveland Cavaliers assistant coach and player Damon Jones, who stands accused of participating in both schemes.

“The fraud is mind boggling,” FBI Director Kash Patel told reporters. “We’re talking about tens of millions of dollars in fraud and theft and robbery across a multiyear investigation.”

The alleged fraud, however, paled in comparison to the riches the athletes earned on the court. Billups, who was inducted into the Basketball Hall of Fame last year, had about $106 million in earnings over his 17-year career. Rozier –who was born in Youngstown and starred at Shaker Heights High School — made about $160 million in his stops in Boston, Miami and Charlotte.

Billups and Rozier have been placed on leave from their teams, according to the NBA, which said it is cooperating with authorities.

“We take these allegations with the utmost seriousness, and the integrity of our game remains our top priority,” the NBA said in a statement.

Hours after his arrest, Rozier appeared in a federal court in Orlando, Florida, wearing a Charlotte Hornets sweatshirt, handcuffs and shackles. Billups appeared before a judge in Portland, Oregon. Both men were ordered released from custody on certain conditions.

Billups’ attorney, Chris Heywood, issued a statement Thursday evening denying the allegations, calling his client a “man of integrity.” “To believe that Chauncey Billups did what the federal government is accusing him of is to believe that he would risk his Hall-of-Fame legacy, his reputation and his freedom. He would not jeopardize those things for anything, let alone a card game,” Heywood said.

Rozier’s lawyer, Jim Trusty, said in a statement that his client is “not a gambler” and “looks forward to winning this fight.” Trusty criticized authorities for not allowing his client to surrender on his own and accused officials of wanting “the misplaced glory of embarrassing a professional athlete with a perp walk.”
