Dundee United have confirmed that they will not be appealing against Danny Swanson's weekend dismissal.
The midfielder saw red during the closing stages of United's 3-2 victory over St Johnstone on Saturday.
He was deemed to have committed a professional foul on Gavin Swankie and was ordered from the field as a result.
United boss Craig Levein was initially uncertain as to whether the tackle warranted such action and had been contemplating contesting the decision.
However, he has since been informed that officials have been urged to clamp down on such tackles - deliberate fouls - by the Scottish Football Association and has been forced to accept that Swanson must now serve a suspension.
"I have spoken to Hugh Dallas (SFA head of referee's development) and he said that, under the directive the referees are given, Danny's tackle merited a red card," Levein told The Courier.
"This season a challenge like that will result in a sending off. As long as that is the case for everyone, we can accept that, so we won't be appealing."
Swanson is now set to sit out United's SPL date with Hibernian on Saturday.
