IFAB had agreed to a temporary change to allow teams to use five substitutes, rather than the usual three, in May to "protect player welfare"
Football's rule-making body International Football Association Board Wednesday said teams will be allowed to continue to use up to five substitutes next season, in a bid to cope with potential fixture congestion in the aftermath of the Covid-19 outbreak.
IFAB had agreed to a temporary change to allow teams to use five substitutes, rather than the usual three, in May to "protect player welfare".
The decision on whether to apply this temporary amendment remains at the discretion of each competition organizer, IFAB added.
Major European leagues such as England's Premier League, Germany's Bundesliga and Spain's La Liga adopted the rule for the remaining games of the extended 2019-20 season.
The 2020-21 campaign will also be affected by the novel coronavirus, with top leagues not expected to start until mid-September.
The Champions League group stage matches have also been pushed to October and will be played over six consecutive midweeks.
IFAB said it will continue to monitor the impact of the pandemic on the game to ensure "appropriate action is taken in the future in relation to this temporary amendment".
