Persson was upset after a Varbergs goal was rejected.
- I thought I was too old to be so damn pissed inside, I think it squirted in my ears.
Now it feels like it's enough, I can not comment on it anymore, he said to SVT Sport after the match last Monday.
Afterwards, Karlsson explained why the goal was rejected and stood his ground.
"Observers on site have verified that he is so close to the goalkeeper that he disturbs him," Karlsson said in SVT's Football Studio.
According to Hallands Nyheter, Persson has been reported for "aggressive behavior" to the Swedish Football Association's disciplinary committee.
- I stand for everything I have said, Persson says to Hallands Nyheter.
