PFA Scotland has stressed that its petition calling for a top-flight ban on artificial pitches was instigated by players and not its officials.
The trade union also defended its decision not to ask players from the three Premiership clubs with the surfaces to sign the document – claiming it was for their own protection.
Kilmarnock striker Kris Boyd criticised the union for not asking the opinions of his squad and players at Livingston and Hamilton in its “survey”.
PFA Scotland said in a statement: “Firstly, and important to note, the Improving Pitches Petition is a petition and NOT a survey as has been misrepresented.
“The petition is PLAYER led, it was NOT initiated by PFA Scotland. It is the players calling for change.
“At this season’s 42 PFA Scotland club visits, the players were very vocal in their frustration at the state of pitches/surfaces they are being asked to play on week-in, week-out across the SPFL.”
The PFA management committee approved the two petitions and agreed it would be unfair to ask Hamilton, Kilmarnock and Livingston players to sign “as by criticising their own club they could potentially be in breach of their contract”.
