Footballers can now play for their clubs until 3 January before leaving for the Africa Cup of Nations, says the Confederation of African Football.
Fifa rules state that clubs have to release players by 27 December for the tournament, which starts on 9 January.
But a letter from Fifa to the World Leagues Forum said Caf had agreed players can turn out in official games for their clubs up to 3 January.
“This decision is taken in the spirit of goodwill and solidarity,” said Fifa.
It means Liverpool will be able to call on Egypt forward Mohamed Salah, Senegal winger Sadio Mane and Guinea midfielder Naby Keita for their game on 2 January at Chelsea, who will have Senegal keeper Edouard Mendy available.
Algeria players Riyad Mahrez and Said Benrahma can play for Manchester City and West Ham respectively, while others will also benefit.
The Africa Cup of Nations runs until 6 February, with Leeds United, Newcastle United, Norwich City and Tottenham the only Premier League teams not losing anybody for the tournament.
