Chelsea loanee David Datro Fofana has been banned from Union Berlin training.

The Ivorian striker refused to shake the hand of coach Urs Fischer when he was substituted in Tuesday's Champions League defeat to Napoli.

Union Berlin spokesman Christian Arbeit has confirmed to Sky Sport that Fofana will not train with the team until next Wednesday.

Fofana will also miss Tuesday's Cup match against Stuttgart.

The striker is on a season-long loan in Berlin.
