Steven Moffat, 21, from Prestonpans near Edinburgh, pleaded guilty to breaching the peace, resisting arrest and drinking in public during a second-round Scottish Cup fixture on Saturday, police said.
He appeared from custody at Haddington Sheriff Court today.
Two other men, aged 17 and 21, have been charged in relation to incidents during the match between junior side Preston Athletic and Scottish League Two side Queens Park.
The game at Pennypit Park, Prestonpans was held up when around 10 people invaded the pitch at half-time.
Police and stewards cleared the pitch and removed around 20 supporters who, officers said, set off fireworks and flares during the game.
The referee restarted the match once the pitch was cleared and Queens Park won 2-1. The game was a replay following a 2-2 draw between the sides at Hampden Park the previous weekend.
Inspector Andrew Harborow said: "It is disappointing that a small group of around 20 people, who claim to be football supporters, disrupted what was otherwise a good-natured family event.
"The total attendance was 806, of which around 100 were travelling fans, the vast majority were there to support their local teams and enjoy a football match.
"Our inquiries are continuing to identify those responsible for the disorder and it is to be expected that the footballing authorities will be looking at the match report with interest."
The early rounds of the Scottish Cup sees clubs from Scotland's bottom professional league play some of the best junior teams in the country. Premier League and Championship teams join the competition in the later rounds.
