St Johnstone manager Steve Lomas has been handed an eight-match touchline ban, his club have confirmed.
Lomas was handed the punishment after being sent to the stand during St Johnstone's 1-1 draw against Celtic last month.
A statement on the Perth club's official website read: "The SFA have this afternoon handed Steve Lomas an eight-match touchline suspension following his dismissal from the dugout in the match against Celtic on 11th November for foul and abusive language towards a match official."
The club added: "This ban consists of six games for the offence committed at Celtic Park plus the suspended two-game ban which was already hanging over him following the game against Ross County in Dingwall in September."
Lomas was also sent to the stand towards the end of his side's 1-0 defeat by Hibernian on Wednesday night.
The Scottish Football Association confirmed Lomas had been punished for breaching rule 203, which incorporates "dissent, the adoption of an aggressive attitude towards a match official and the use of offensive, insulting and abusive language".
Lomas had apologised to referee Iain Brines after hitting out at his decision to allow Celtic striker Tony Watt back on to the field following treatment in what he felt was a dangerous position.
The former Northern Ireland international said after the game: "I have been in to see Iain and I have apologised for my language but it is a highly emotional game and I would have been very unhappy if they had scored."
The apology was not enough to secure leniency from the SFA's fast-track tribunal, who also upheld dismissals for Motherwell goalkeeper Darren Randolph and Kilmarnock captain Manuel Pascali.
