The Turkish SuperLig has been suspended indefinitely after a referee was punched by Ankaragucu's president following a 1-1 draw with Rizespor, the country's football federation (TFF) announced on Monday.
Ankaragucu chief Faruk Koca floored referee Halil Umut Meler with a vicious punch to the face on the pitch following Monday's game, leaving the official with a black eye.
"This vile attack was not only made against Halil Umut Meler," the TFF said.
"Today, this inhumane and despicable attack was made against all stakeholders of Turkish football.
"In coordination with our State, all the criminal proceedings they deserve have been initiated against those responsible and instigators of this inhumane attack.
"The responsible club, the Club President, its managers and all the criminals who attacked Halil Umut Meler will be punished in the most severe way.
"By the decision of the Turkish Football Federation Board of Directors, matches in all leagues have been postponed indefinitely," it added.
Rizespor had equalised during injury time before Koca made his way onto the field and attacked Meler.
Meler fell to the ground and was hit again while on the floor in the middle of a melee of players, coaches and officials.
According to local media Meler was the transferred to a hospital due to his injuries.
Turkish president Recep Tayyip Erdogan condemned the incident which took place in the capital city, Ankara.
"Sports means peace and brotherhood. Sport is incompatible with violence," Erdogan posted on Twitter, which is being rebranded as 'X'.
"We will never allow violence to take place in Turkish sports," he added.
The next and 16th round out of 38 of the Turkish top-flight was scheduled for next weekend.
