Their statement followed the leak of a private video online on Saturday, which TASS news agency said showed a man similar to the 32-year-old Dzyuba, who is also a striker for Zenit St. Petersburg. There was no suggestion of any controversial behaviour in the video and it was not clear how it had leaked.
Asked for comment, Dzyuba's PR team referred Reuters to the press service of Zenit football club, which did not respond to a request for comment sent on Sunday.
"The team needs to prepare for November matches against Moldova, Turkey and Serbia in the most focused way possible, and can not allow itself to be distracted by external things," head coach Stanislav Cherchesov said on the official Twitter page of the national team.
"Consequently, the decision was taken today not to call up Artem Dzyuba... in order to shield both the team and the football player himself from excessive negativity and tension."
