New Delhi: World champion P V Sindhu has pulled out of next month's Uber Cup due to "personal reasons" and could also miss the subsequent Super 750 tournaments in Denmark.

The Thomas and Uber Cup, scheduled to be held from October 3 to 11 in Aarhus, Denmark, is the first tournament in the revised calender, which was launched by the sport's governing body BWF last week.

"Sindhu will not be able to participate in the Uber Cup due to some personal reasons," the Olympic silver-medallist's father P V Ramana told PTI.

"She has some personal work, so unfortunately she will have to skip the event. We have informed the Badminton Association of India about her decision," he added.

The tournaments will be followed by the Denmark Open I (October 13-18) and Denmark Masters (October 20-25).

Sindhu, who has been training at the national badminton camp in Hyderabad, had been planning to participate in the prestigious tournament.

Asked if she would be participating in the two 750 events in Denmark, Ramana said: "Actually that is also (in doubt) ... I mean the entries have been sent for both the events, but it depends on her personal work if she would be able to play both or not.

"She may have to skip one tournament in Denmark. If she can complete her personal work then she will play one."

Sindhu had resumed training last month under the supervision of Korean coach Park Tae-Sang after the Sports Authority of India (SAI) allowed the national camp for eight Olympic hopefuls following approval from the Telangana government on August 1.

Besides Sindhu, world championship bronze medallist B Sai Praneeth, former world No. 1 Kidambi Srikanth and women's doubles player N Sikki Reddy are the only ones currently training at the SAI-Pullela Gopichand Academy.
