Turkish football bosses suspended all leagues after a referee was punched to the ground by a club president following a top-flight game on Monday, the BBC reports.
Halil Umut Meler was struck by MKE Ankaragucu president Faruk Koca, who ran on to the pitch after his team conceded a 97th-minute equaliser in a 1-1 Super Lig draw with Caykur Rizespor.
“The matches in all leagues have been postponed indefinitely,” Turkish FA [TFF] chairman Mehmet Buyukeksi said in a news conference.
“This attack is a night of shame for Turkish football,” he added.
Meler received several blows from others as he lay on the turf and suffered injuries including a minor fracture.
The incident sparked chaotic scenes involving players and club officials.
