Lionel Messi will not play competitive football for Barcelona for the next three weeks after getting a groin injury in the draw with La liga rival club Atletico Madrid on Wednesday night.
He went off on 59 minutes on Wednesday after a Diego Godin tackle.
The Argentina captain was forced to miss Argentina's World Cup 2018 qualifier against Venezuela earlier this month with a groin injury, but has played in all five La Liga games this season.
The Argentine could return for Barca's Champions League tie with Manchester City on 19 October.
