Callum Davidson called for refereeing consistency after St Johnstone’s opening day defeat to Hibs.
Referee Euan Anderson flashed a second half straight red at midfielder Murray Davidson for a late challenge on Ryan Porteous.
Perth boss Davidson felt, if that was worthy of a red, so was the tackle of visiting full-back Marijan Cabraja on Ryan McGowan as the game reached its latter stages. Only a yellow was shown.
