Kilmarnock manager Kenny Shiels is looking for answers over the Scottish Football Association's disciplinary system after his captain was among two players to lose appeals during a session that left St Johnstone boss Steve Lomas facing an eight-match ban.
Shiels hit out after Rugby Park defender Manuel Pascali lost his appeal against his dismissal for a challenge on St Johnstone forward Nigel Hasselbaink.
Motherwell goalkeeper Darren Randolph had earlier failed in his challenge against a two-match suspension as he was found guilty of violent conduct over his clash with Hearts striker Callum Paterson.
And Lomas was later handed a six-match ban for an angry reaction towards referee Iain Brines over a decision during his side's draw at Celtic Park this month, with a suspended two-game punishment also invoked.
Shiels, who was hit with two SFA charges earlier this week, told STV: "The referee (Stevie O'Reilly) made a mistake. It was a blatant mistake. How they have come to this decision is quite unbelievable.
"We need answers. I want to see the report.
"I've lost a lot of faith in the system because the system isn't working."
