Premier League clubs in Tier 4 areas will be tested for Covid-19 twice a week as soon as it is practically possible to do so, reports SkySports.
Players and staff at top flight clubs have been tested on a weekly basis since the start of the 2020-21 season but testing at clubs in Tier 4 areas will now revert to the level used during 'Project Restart' in the summer.
The increased testing will be widened out to clubs in lower-tier areas from next month.
The Premier League clubs currently in Tier 4 are Arsenal, Chelsea, Crystal Palace, Fulham, Tottenham and West Ham.
