SFA panel finds four major errors involving Rangers, Hearts, Hibs and Aberdeen in bad weekend for referees

The incorrect decisions flagged by the Key Match Incident panel included the red card shown to Rangers midfielder Mohamed Diomande in the 3-1 win at Dundee United, which had already been rescinded after the Ibrox club won their appeal against the dismissal earlier this week.

The Ivorian was sent off late on at Tannadice Park on Sunday after an incident with Kevin Holt, with referee Nick Walsh sticking with his original verdict despite a VAR review, much to the anger of Rangers manager Philippe Clement, who branded the decision "incredible".

The KMI panel, which meets weekly and is made up of five individuals from within Scottish football circles, came to the unanimous conclusion that the colour of card was wrong.

"The panel unanimously agreed that the on-field decision was incorrect," the report stated. "The panel believed VAR was correct to intervene and recommend a review. The panel believed the referee should then have reversed his decision and downgraded the red card to a caution."

Elsewhere, Hibs protestations that they were on the wrong end of two incorrect penalty decisions in their 1-1 draw at Ross County were only partly vindicated. The KMI panel found, by 4:1 majority, that the decision to penalise Nicky Cadden for a handball in the 26th minute of the match in Dingwall was wrong although justice was done when Hibs goalkeeper Jordan Smith saved Jordan White's spot kick.

However, the decision to award Ross County a second penalty late on for a foul by Smith on Ronan Hale was unanimously supported by the KMI panel, despite Hibs manager David Gray branding both penalty decisions "extremely soft".

Another major mistake was highlighted in allowing Hearts' opening goal to stand in the 3-2 win over Kilmarnock at Tynecastle. Elton Kabangu put the home side ahead in the sixth minute but had been in an offside position and interfering with play earlier in the move. The KMI report stated: "The panel unanimously agreed that the on-field onside decision was incorrect. The panel highlighted VAR should have intervened and the goal should have been disallowed for offside."

There was also a missed red card in Aberdeen's 3-0 defeat to St Mirren. The KMI panel found that Saints defender Scott Tanser should have been sent off for a handball which denied the Dons a goalscoring opportunity in the 59th minute while the away side were leading the match 2-0.

The report stated: "The panel discussed this decision at length with the majority (4:1) deeming the on-field decision incorrect. The majority (4:1) believed that VAR should have intervened and recommended an OFR for a red card. One member of the panel highlighted that they didn't think it was an obvious goal scoring opportunity and a VAR intervention should not take place, although a yellow card should have been awarded."

The KMI panel reviewed 10 decisions in total meaning that 40 per cent were found to be incorrect with St Johnstone v Motherwell the only fixture to remain error-free.
