The ASEAN Basketball League (ABL) has announced a partnership with the Indonesian basketball regulatory organization Persatuan Bola Basket Seluruh Indonesia (PERBASI) and the Indonesian Basketball League (IBL), agreeing that all players who have been registered by clubs from either leagues cannot be registered in the other during the season.

With this partnership with the ABL, we ensure that both leagues have the best available players for all clubs participating, and at the same time respecting each other’s league calendars,” said IBL President Hasan Gozali in the official release.

This is believed to prevent players from doing double-duty or transferring leagues while in the middle of the season. Fans will remember how Satria Muda competed in both leagues simultaneously in the past. They even won both the 2012 Indonesian Championship and the ABL crown (as Indonesian Warriors) in the same year.

According to Mainbasket, a similar situation applied to Hang Tuah during the 2013-2014 season, when a bulk of their players later competed in the ABL as the short-lived Laskar Dreya South Sumatra.

One downside to such a rule is that it could prevent players, including imports, from securing another job if they get cut or replaced by their mother club mid-season.

Additionally, the agreement also appears to aim on preventing any future clubs from leaving the IBL and joining the ABL like the CLS Knights Surabaya, as they would have to secure the approval of both PERBASI and the Indonesian league first.

“It is only right that the ABL respects each country’s domestic league and its National Federation’s regulations. Just like all teams in the sport of basketball, teamwork is key to development and success,” added ABL Chief Operating Officer Jericho Ilagan.

The ASEAN Basketball League will tip off on 17th November, while IBL Indonesia begins on 8th December.
