Liverpool's clash with Tottenham Hotspur has been moved from White Hart Lane back to Wembley.
Spurs had already received special Premier League dispensation to move their home stadium part way through the season, and the opening of their new White Hart Lane stadium was due to take place for the trip by the reds next month.
However, the 15th September game will now revert back to being played at the national stadium.
Spurs have also moved their 6th October game against Cardiff to Wembley and they have yet to decide where they will be playing their next home game - they face Man City on the 28th October.
Spurs new ground will house just over 62,000 supporters and features an impressive design. It includes modern football features such as 'a new open food court bathed in natural light', a 'dramatic skywalk provide stunning views' and obviously a fully utilised microbrewery.
A statement by the London club read:
"Recent testing and commissioning has now shown issues with the critical safety systems.
"We are reviewing the situation and planned timetable to rectify and re-test, after which we shall be in a better position to outline a revised timetable.
"The delays created by these difficulties mean that we can no longer hold the necessary test events on 27 August and 1 September. These will need to be rescheduled to take place ahead of any first official match at the new stadium in order to achieve the safety licence."
Liverpool are unbeaten in their last four visits to White Hart Lane, with two wins (5-0 and 3-0) and two draws.
