Two more stadiums for the 2018 World Cup in Russia have fallen behind schedule, this time in the cities of Volgograd and Nizhny Novgorod.
An amendment to spending plans published on a Russian government website has changed to 2018 the dates when both stadiums will be ready for use. They had previously been listed for completion in December 2017.
The new document did not specify exactly when in 2018 the two stadiums, which will each hold 45,000 fans, would be completed.
The delays at the Nizhny Novgorod and Volgograd stadiums follow earlier troubles at other arenas, most notably the 68,000-seat stadium in St. Petersburg, which has endured repeated delays and cost increases in a decade-long construction project.
World Cup organisers have not commented on the latest delays, but have previously said they expect all stadiums to be ready for the tournament.
