According to the announcement on Facebook, KeSPA chairman Jun ByungHun said "the drop in the number of ProLeague teams and players, difficulty securing league sponsors, and match fixing issues have made it challenging to maintain ProLeague."
The ProLeague was formed in 2003. "The decision to put the past 14 years behind us and discontinue ProLeague was a difficult one and it deeply saddens me to have to also bring you the news that KeSPA will be stopping its operations of ProLeague teams," said Jun Byunghun.
