This month's Carabao Cup final between Manchester City and Tottenham Hotspur will be allowed to host 8,000 spectators as part of pilot events to pave the way for the return of large crowds to stadiums.
The final will be held at London's Wembley Stadium on 25 April. It was due to be played on 28 February but was pushed back in the hope that a later date would allow fans to attend.
"The Department of Culture, Media and Sport has given the green light for 8,000 spectators to attend as part of the UK Government's Events Research Programme," City said in a statement
Tickets will be made available to both Tottenham and City fans as well as local residents around the stadium and the National Health Service (NHS) workers.
The trial, to be run at nine events including the FA Cup final and one semi-final, will be used to assess whether large events can be held in closed settings without social distancing.
The FA Cup semi-final between Leicester City and Southampton on 18 April will be allowed to host an audience of 4,000, while a crowd of 21,000 will be permitted for the final on 15 May.
Both matches will be held at Wembley.
