The 21 year old has been punished for staying out late with team mates Sidnei and Julio Alves.
Now he has been prevented from training with the first team, but the length of time the ban will remain in place is not known, only to the club.
"This is not the place to vacation. Besiktas have rules and discipline which the players have to obey,"Beskitas coach Tayfur Havutcu is quoted in saying in the Daily Mail.
"It is not allowed, except in reasonable hours, to be inside nightclubs.
"This was a joint decision between myself and the club administration. At this stage, it is not possible to say how long the penalty will last. It could be one week and then forgotten or the players could stay out of the squad until the end of the season.
"It all depends now on their performance in training. Alves, Bebe and Sidnei will continue to work according to this programme."
