Burnley have issued sanctions against 12 people following a minor pitch invasion against Preston on 22 April.
The sanctions range from stadium bans to acceptable behaviour agreements.
“There are still several fans who ran onto the pitch, but have not been identified. Club officials will continue to use CCTV to identify these supporters in the coming weeks,” the club, now in the Premier League, added.
“In order to prevent the club from being in jeopardy of receiving a heavy fine from the FA, fans are again respectfully requested to stay within the seating area at Turf Moor and when visiting other clubs.”
