SPL chiefs will open a Perth pitch probe on Monday morning after the late call-off Saturday's clash with Rangers at McDiarmid Park. Undersoil heating failed to thaw out one goalmouth with the game called off an hour before kick-off, reports the Scottish Sun.
St Johnstone chairman Geoff Brown has promised an internal probe.
An SPL spokesman said: "We are very disappointed at the postponement. The next step is to get all the reports from the clubs, the officials and the match delegate.
"We must have pitches in proper condition to get games on. We have to look at whether more could have been done or if there has been a breach of rules."
Saints have pledged to cut £2 from admission prices when the game is rearranged. Brown said: "Obviously I'm not happy about what happened and I don't know the full details yet. But questions will be asked.
"It's never happened before so we will have to assess the situation quickly and get to the bottom of it.
"The undersoil heating had been on and no one had anticipated a problem.
"We are not yet in a position to say what has happened.
"We'll have a maintenance crew in to have a look at it.
"I am really disappointed for everyone, including manager Derek McInnes and his players who were coming off that great 5-1 win over Hibs and were raring to go. Something like this really knocks you back and I know everyone at the park was gutted.
"I don't think any club has cut prices like this. It is a gesture towards the fans who were inconvenienced and frustrated."
