Yoe Flash Wolves' PartinG will be unable to compete in the upcoming season of Proleague, according to a report from DailyEsports. The former SK Telecom T1 player was originally set to compete in Proleague as a part of the Startale-Yoe alliance, but contract regulations have barred him from the tournament.
Contrary to previous reports, PartinG did not leave SK Telecom T1 at the end of his contract as a free agent. KeSPA regulations require a player to play on a team for at least five years to obtain free agent status (clarification via DES reporter Kenzi). As PartinG left SK Telecom before this period, KeSPA has designated him as a player who has 'arbitrarily left' left his team. In such cases, the player's contract is suspended while all rights to player remain with his original team.
According to DES, PartinG is only eligible to play for SK Telecom T1, unless SKT puts in a request to the KeSPA chairman to free PartinG from the restriction.
Furthermore, Rain and FanTaSy are also said to fall under the same restriction, although their contracts had ended in September. Though both players have played with SK Telecom for over five years, neither player had filled the requisite five years since their previous free agency.
TL;DR: PartinG, Rain, and Fantasy cannot compete in Proleague this season, unless it is for SK Telecom T1. The reason is that they did not leave SKT as free agents, leaving their Proleague rights remaining with SKT. This is due to KeSPA regulations where players must fill a certain length of time on their contracts before being eligible for free agency status.
