Tottenham has confirmed that the contingency plan has been created by Wembley to host home games for the rest of the season.
Spurs planned to move to their new stadium, only a few years ago, only delaying construction for a third time in three months.
The club still wants to move to its new home before the end of the current campaign, insisting that this agreement will only remain in view of possible delays in the future.
The statement says: "As an emergency measure to ensure that we can play games while we look forward to the exact date of the new stadium's opening, the club has reached an agreement with the WNSL to host other home games that we may have to take on Wembley Stadium."
It adds: "As already mentioned, we will try to provide additional information on the development of the stadium in December."
Before earning the Football Association Safety Certificate, Spurs must complete two successful test measures on the ground.

Toby Alderweireld recently admitted that delays had an effect on the team and told reporters: "We never used Wembley as an excuse, and we will not do it now, but it has affected us."
