St Johnstone midfielder David Wotherspoon has been suspended for three European games and the Perth club and Aberdeen fined after their Europa Conference League exits.
Aberdeen must pay £4,300 following a pitch invasion during their 3-1 defeat by Qarabag at Pittodrie.
St Johnstone have been fined £1,900 by European governing body Uefa because of objects thrown as they lost to LASK.
Wotherspoon was sent off within a minute of coming on as a substitute.
The 31-year-old was shown a straight red card at McDiarmid Park for elbowing opposition midfielder Florian Flecker during the 2-0 loss and Uefa imposed the ban "for assaulting another player".
