Safe standing will not be trialled in England's top two leagues this season, despite a new report suggesting controlled tests would have value, reports BBC Sport.
The government-commissioned report said more evidence was required before safe standing could be adopted.
Standing in English football's top two tiers is illegal after recommendations made following the 1989 Hillsborough disaster when 96 fans died.
But evidence will be gathered in stadia outside the top two tiers this season.
The latest development means safe standing will not come into force until at least 2021, but once evidence has been gathered there is likely to be a public consultation, meaning it could be 2022 before safe standing might be introduced.
