A National Basketball Association player and coach are two of several people across the country who have been charged in illegal sports betting cases, according to the BBC’s US partner CBS News.
Miami Heat player Terry Rozier was among six people arrested, including other players who may have faked injuries, according to reports.
Portland Trail Blazers coach Chauncey Billups, meanwhile, is one of 31 people charged in a separate illegal poker game case involving coaches and organised crime figures, law enforcement sources told CBS.
Prosecutors in New York and Federal Bureau of Investigation Director Kash Patel are expected to hold a news conference at 10:00 EST (15:00 BST).
The BBC has contacted the NBA for comment.
Federal investigators had been probing unusual betting activity related to a March 2023 game Rozier played for the Charlotte Hornets, according to CBS.
Officials were investigating whether Rozier manipulated his performance in the game for an illegal sports gambling scheme, according to The Athletic.
During the game, Rozier played roughly nine minutes and scored just five points against the New Orleans Pelicans because of a sore right foot.
Before that game, he averaged 35 minutes of playing time and about 21 points per game.
