Hamburg defender Slobodan Rajkovic has been suspended by the club until further notice after a training ground bust-up with Son Heung-min on Friday.
The pair came to blows after exchanging insults during training, with Tolgay Arslan, who was nearby, needing treatment for a cut after accidentally being struck in the head during the melee.
Hamburg coach Thorsten Fink has blamed former Chelsea man Rajkovic for the incident and suspended him from training with immediate effect.
According to the Bundesliga club's official website, he will not join the squad on their tour of South Korea over the coming weeks while Son can also expect punishment in the form of a fine.
If and when Rajkovic will return to training remains unclear.
