The sweeping, multipart federal gambling investigation led to the arrests of Rozier, Portland Trail Blazers coach Chauncey Billups and more than 30 other individuals. The NBA placed Rozier and Billups on immediate leave soon after the arrests, with the league saying that it was reviewing the indictments.

Portland Trail Blazers head coach Chauncey Billups has been charged in an illegal poker operation tied to the mafia, law enforcement sources told ABC News.

Chauncey Billups is one of multiple former Celtics who was arrested by the FBI in connection to illegal gambling schemes.
