Billup's was arrested on October 23rd, but not for the reasons that you listed. Chauncy Billups was arrested for rigging high stakes poker games across multiple cities including Miami, Las Vegas, the Hamptons, and many more. In none of the documents it says that he was arrested for providing team injury information. On October 23rd there were just over 30 arrests for this enormous scheme involving a lot of people that represent the National Basketball Association (NBA) including Terry Rozier. This was a big shock for a lot of people across the country and makes you question how big this scheme was. So although Chauncy Billup's was arrested, those weren't the specific charges that he was arrested for.
