Authorities announced 31 arrests Thursday in 'Operation Royal Flush,' alleging a mob-linked ring rigged underground poker with X‑ray tables, hidden cameras and altered shufflers. Charged are Portland Trail Blazers coach Chauncey Billups and ex-NBA player Damon Jones; Miami Heat guard Terry Rozier was named in a separate indictment alleging misuse of nonpublic game information, claims his attorney disputes. Prosecutors say more than $7 million was taken, with threats and assaults used to collect debts. Four New York Mafia families allegedly backed games tied to Bonanno and Gambino crews. The NBA placed Billups and Rozier on leave.
