Talisca, the Brazilian midfielder who has been a key player for Crystal Palace this season, was absent from their match against West Bromwich Albion on Sunday.
The news comes as a blow to Palace, who were hoping to build on their impressive start to the season with a win at The Hawthorns.
Talisca, who joined Palace on loan from Everton earlier this year, has made a strong impression since his arrival and has become a fan favourite at Selhurst Park.
However, his absence will be a big miss for the Eagles, who will have to rely on their other midfielders to step up and provide some much-needed creativity and energy in attack.
Palace will now look to bounce back from this setback and continue their promising start to the season, while also keeping an eye on the potential return of Talisca should he recover in time for their next match.
