Real España defender Marlon Peña lost his temper with a particular opposition fan by kicking him in the head in a post-match pitch invasion.
With both sets of supporters on the pitch, Peña decided to take matters into his own hands by sprinting towards a fan and launching a karate-like kick to his noggin before he retreated.
The pitch invasion was sparked after Club Deportivo Marathón defeated Real España 2-0 in the play-off quarter-finals with goals from Mario Berrios and Johnny Leverón either side of the interval.
However, this wasn't enough for Marathón to overcome the first-leg deficit and they were eliminated on the night 4-3 on aggregate.
After the game finished, Marathón supporters were left frustrated with their side's failure to progress in the cup so they stormed the pitch and started attacking both sets of players. Real España fans also found a way onto the pitch but the police managed to restore parity after 10 minutes.
After the recent pitch invasions from the football league play-offs, it's quite fortunate there haven't been more incidents like this.
However, there have been allegations that Chesterfield captain Ian Evatt was punched, kicked and spat on by fans following a pitch invasion in last weekend's play-off defeat at Preston.
Evatt used to play for Preston's Lancashire rivals Blackpool which may have been the reason for supporters targeting him. I bet that particular supporter is breathing a sigh of relief that he didn't react in the same manner Peña did!
