Paris - Just as global sports had rediscovered its brio and the welcome return to full stadia, the Omicron coronavirus variant threatens to once again plunge it into chaos.
AFP Sports casts an eye over the state of play in various sports across the globe, including the Premier League, Africa Cup of Nations and India’s cricket tour of South Africa.
Brentford manager Thomas Frank has called for a circuit break of the season as positive tests pile up across several clubs and it enters one of its most hectic spells of matches.
Jurgen Klopp disagreed with him but with postponements increasing -- five of the matches due to be played on Saturday and Sunday have been called off -- the BBC reported Premier League clubs were due to meet on Monday to discuss the spiralling crisis.
Africa Cup of Nations
The biennial African football showpiece to be hosted in Cameroon in 2022 has already been postponed from this year. Now it is under threat again.
European clubs have strongly hinted they will not release their players due to fears surrounding the Confederation of African Football's (CAF) Covid-19 health protocol.

"There is a big question surrounding whether it will happen or not."
The Spanish football giants have had a swathe of positive tests during the week: six players including playmaker Luka Modric and assistant coach Davide, son of coach Carlo Ancelotti.
Only two of the players, though, started the previous La Liga match and for the moment Sunday's match against Cadiz is on as under Liga protocols a club must have at least 13 players, at least five of them first-teamers and one a goalkeeper, available to play a match.

European Champions and Challenge Cup
The EPCR board meet to discuss whether the six Champions Cup matches involving English and French sides can take place following the French government's stringent travel protocols between the two countries due to take effect from 2300 GMT on Friday.
Three matches have already been called off the Champions Cup games between Montpellier and three-time winners Leinster -- due to the Irish side having covid cases -- and Racing 92 hosting Welsh side Ospreys and a Challenge Cup match between Pau and Premiership side Saracens.
All three French sides will be awarded the points as unlike the Premier League there is no leeway to play the matches later.
Pakistan v West Indies
Covid has already forced the cancellation of a one day series -- part of the qualifying round of the 2023 World Cup -- between Pakistan and the West Indies due to start this weekend with five members of the tourists squad testing positive on Thursday. Officials said those who tested positive will have to isolate in Karachi before being allowed to travel home.

The tour is of crucial importance to the cash-strapped host body, which announced a R221-million (about $13.8-million) loss at its annual meeting in October.
