Turkish side Adana Demirspor walked off the pitch 30 minutes into their Super Lig game at Galatasaray on Sunday as they trailed 1-0 to a penalty.
The decision to walk off was taken to protest to Turkey's referees committee and football federation, Adana Demirspor President Murat Sancak said according to news website T24.
Sancak said smaller clubs were treated unfairly and their issues were not resolved, T24 reported, without giving details.
Bottom side Adana Demirspor were losing to a 12th minute spot-kick that was scored by Galatasaray's Spanish striker Álvaro Morata.
Galatasaray coach Okan Buruk said in an interview after the visitors had walked off the field that the penalty could have been an incorrect decision.
