Former Denver Broncos running back and current CBS4 sports anchor Reggie Rivers is the biggest name being associated with an illegal gambling ring that may have ties to a New York Mafia family. CBS4 says it is “aware that Reggie Rivers is on the witness list” and that its management has “been informed that (Rivers) is fully cooperating with the CBI.” Tom McGhee and Deborah Sherman at the Denver Post have the details.

UPDATE: Rivers tells 9News he was unaware that gambling is illegal in Denver, and the CBI is treating him as a potential witness rather than a target of its investigation.
