Magistrates opted against issuing a banning order to Simon Rusling, but the pitch invader was fined £370 for the offence, as well as being ordered to pay court costs of £85 and a £37 victims' surcharge.
The incident happened during the Iron's 3-1 victory over Swindon Town at Glanford Park on Saturday, April 27 – after which the club were relegated to League Two.
The game was marred by ugly scenes in the Grove Wharf Corner and the car park at the final whistle.
