More revelations in the tennis match fixing saga.

An ABC Four Corners investigation has found more than 40 professional players were flagged for potential match-fixing by international bookmakers, in a three month period last year.

The matches took place at tournaments in countries including Colombia, Morocco, Russia and Germany between September and November.

The investigation has obtained a blacklist containing more than 350 names which Four Corners has provided to tennis authorities.
