The centre-back, along with England Under-21 assistant coach Steve Wigley and Leeds defender Tom Lees, has been charges following the post-match brawl in October
Tottenham manager Andre Villas-Boas has backed Steven Caulker to remain focused on his on-field duties in light of police charges in Serbia.
The Spurs defender was caught in the middle of the post-match melee after England Under-21’s European Championship play-off victory over Serbia in October following Danny Rose’s reaction to alleged racial abuse from the crowd.
Leeds United defender Tom Lees and assistant Steve Wigley have also been accused of wrongdoing, with the FA and the players' clubs expecting to hear formally about the charges in the near future.
"At the moment we don’t have enough information, nor do the FA," Villas-Boas told The Sun.
"There is contact between the FA, the government and the embassy in Serbia to try to find out more information about the speculation that is coming out, and we've spoken to the player."
Caulker has made a positive start to the campaign following an impressive loan spell at Swansea City last year, with his manager expecting his run in the team to continue in Saturday’s visit of Wigan.
"I think he will be ready to play," Villas-Boas admitted. "I think he obviously has a good chance because he has been doing quite well to make selection.
"I am not worried yet with the consequences of what can happen. We are still finding out more information."
