Nikola Djurdjic came under fire last weekend after pictures of him at a nightclub in Stockholm were circulated on social media.
The next day he was to play a match in Uppsala against Sirius.
This caused Degerfors to act and was kicked from the match squad.
Now the Serb apologizes in an open letter on Degerfors' website.
- I want to apologize to my teammates, my coaches and above all the club's supporters, he writes on the club's website.
"Don't drink a drop"
The 36-year-old understands that his behavior was not appropriate, and that he always strives to be professional.
- Last week I broke my judgement, and even though I didn't drink a drop of alcohol, I understood that it was inappropriate to be out the night before a match.
Degerfors lost 0–2 against IK Sirius and Djurdjic was heavily criticized on social media after his actions before the match.
- I realize that being seen out the day before the match is not appropriate, and therefore I apologize.
I have always been professional throughout my career and always gave 100% in training and matches, for all the clubs I played for.
The striker has scored three goals in 20 Allsvenskan matches for Degerfors.
