AIK was down 0-1 in tonight's match against Kalmar when the strange scenes took place.
The guests would replace Bojan Radulovic and Yasin Ayari with Henok Goitom and Erick Otieno.
But the latter remained on the field for over 30 seconds and the Kalmar players got angry.
Otieno did not understand the change, but after a while the referee Andreas Ekberg realized that something was wrong.
He blew off and counted the AIK players and solved, in communication with the fourth referee, the situation.
- You manage to be a man for more than a period without being punished, says Henrik Rydström according to Expressen.
The match then ended 1-1.
