In the second half of Wednesday’s match at Pittodrie, the midfielder let his frustration boil over as he took the legs away from his opponent after the whistle had sounded.
Referee Willie Collum was right on the spot and showed a yellow card to the 21-year-old. Under SFA rules, the compliance officer could have issued further punishment to the player if the match official admitted to not seeing the incident in its entirety.
However, the football governing body have concluded that wasn’t the case here and no other punishment shall be taken.
