"We take these allegations with the utmost seriousness, and the integrity of our game remains our top priority."

Billups, a former Detroit Pistons star and a member of the National Basketball Association Hall of Fame, was arrested in connection with rigged illegal poker games tied to Mafia crime families, FBI Director Kash Patel said earlier in New York.

Rozier and a former NBA player and assistant coach, Damon Jones, were among six people arrested in a sports betting case, Patel added.
