US federal prosecutors announced that a key participant in a college basketball match-fixing scheme received a six-year sentence.
Authorities said the operation involved payments designed to affect results against betting spreads.
The Department of Justice described dozens of players and numerous games connected with the scheme.
The prosecution also included a separate firearms offence for the sentenced individual.
The case has revived debate about student-athlete earnings and the expansion of sports betting.
The issue is how to protect competition integrity through enforcement, education, financial support and gambling regulation.
