The publication of a final report into Russian state-sponsored doping and corruption at the Sochi Olympics has been delayed to December.
The World Anti-Doping Agency says Canadian law professor Richard McLaren expects to release his second report in "early December."
McLaren's interim report in July implicated Russian minister Vitaly Mutko and more than 20 summer and winter sports.
It led WADA to call for a Russian ban from the Rio de Janeiro Olympics.
WADA wanted McLaren to finish by mid-November, when it has board meetings in Glasgow, Scotland.
The latest target confirms McLaren's prediction last month at a FIFA-hosted conference that his work was "at least several months away" from completion.
WADA appointed McLaren in May to investigate corruption claims by Grigory Rodchenkov, the former Moscow testing laboratory director.
