St Johnstone manager Steve Lomas has been given an eight-match ban by the Scottish Football Association.
Lomas was sent to the stands after using foul and abusive language towards an official during his side's 1-1 draw with Celtic at Parkhead on November 11.
The 38-year-old's punishment was increased from six games due to a suspended ban that he picked up following a match against Ross County on November 1.
A further suspension could yet be imposed on Lomas after he was sent to the stands again during Wednesday's 1-0 defeat to Hibernian.
