The Russian is yet to make a Premier League start this season for third-placed Spurs, with the 30-year-old's involvement restricted to the Europa League, which the club exited at the group stage.
Having been strongly linked with moves to Spartak Moscow and Anzhi Makhachkala, Pavlyuchenko was expected to leave the club, however his agent had confirmed that Spurs have taken the option to extend his contract by a further 12 months.
“Tottenham, headed by Mr Levy, had the option of extending his contract, and they have done so," his agent Oleg Artemov told championat.ru.
"They informed UEFA, FIFA and the English FA that they have extended the contract by a year.
"This happened about two or three months ago, so this is already quite old news.”
Pavlyuchenko finished as Tottenham's top scoring striker last season with 14 goals, ahead of Jermain Defoe and the departed Peter Crouch, but has netted just four times in 13 games in this campaign.
The permanent departure of Robbie Keane, who spent last season on loan at Celtic and West Ham United, appeared to pave the way for Pavlyuchenko to lead the club's fight to qualify for the Champions League.
However, the loan signing of Emmanuel Adebayor from Manchester City leaves the Russia international down the pecking order again, with Defoe often preferred as the alternative in the absence of the Togolese forward.
