Not only both teams but bookies should also take out all the matches in the entire league to prevent further bettings on that fixed match.
Besides, removing those will not give a heavy toll on those bookies since if I'm not mistaken, the betting market on that league where the fixed match happened is not that impressive. And the league itself already has a bad reputation. Why there are still bettors betting on that league?
God bless that country where fixed matches are just a simple thing to do.
