Under a substantial, hardline adjustment in Covid cancellation criteria being explored by the Premier League, clubs may soon have to present proof of Four positive tests in their squads to have a match postponed. A shift from "available players" to "active Covid cases" has been considered in crisis discussions between the league and its members, has already received support from as many as 18 teams and might be implemented for the next round of matches. Currently, teams requesting a match be canceled must demonstrate that they do not have 13 eligible players plus a goalie, considering injuries and absences for international duty. This has resulted in 22 postponements and increased animosity between teams after it was revealed that Arsenal was able to get the North London derby postponed despite only having one verified positive case. Calling off the Match Instead, a team would have to present confirmation of four positive tests within its playing group to request a match be called off, according to reports. And that number would be regarded as a 'minimum requirement,' rather than an immediate cancellation trigger. credits - newscon.net After being stung by criticism and an outburst of hatred and accusation among top-flight clubs, chief executive Richard Masters has acted and called every club to gauge their views on the switch and is thought to have strong support, even though there is no official meeting scheduled until February 10.

This would not require a vote of at least 14 clubs and may eliminate the threat of legal action, though top-flight sources insist such is not the case. Some clubs may be requested to formally state that they will not sue if the change is implemented. There are concerns that if it goes to a vote, individuals who vote in favor will be unable to pursue legal action in the future. ‘It’s a minefield,’ said one official. ‘They’re trying to shut the door after the horse has bolted and the ramifications are endless.’ The Premier League did not respond to a request for comment.
