Steve Clarke has been hit with a two match suspension just days before he could be appointed Scotland boss.
He has also been given a further suspended one match ban until 31 December 2019.
The Kilmarnock manager had claimed Steven McLean should never referee another game involving his club after the 1-0 defeat to Aberdeen.
Clarke was at Hampden for a hearing that lasted four hours before being handed the ban.
Killie had three players sent off and Clarke insisted McLean was overcompensating for the fact his dad was a Kilmarnock legend.
Stuart McLean played more than 500 games for the club over 16 years and Clarke felt it had an impact on his son.
Clarke had said: "Since I've been here, he's always seemed to struggle with Kilmarnock games.
"Maybe, or definitely, that's because his father was a player here for so many years. Whether he feels the pressure of that, it seems to affect his performance.
"I have mentioned privately that maybe Steven shouldn't referee Kilmarnock games just to take that burden, that extra pressure, off him. Now I'm saying it publicly.
"I think it would be better for Steven as a referee and for Kilmarnock as club."
The ban means Clarke will be in the stands for Kilmarnock's final game of the season against Rangers at Rugby Park on Sunday.
It’s unclear if he held talks with the SFA over the Scotland job.
The 55-year-old is on a three-man shortlist alongside Aberdeen boss Derek McInnes and Scot Gemmil.
