The 29-year-old picked up the problem while representing Brazil in a friendly against Australia, prompting an early return to Catalonia.
Although medical assessments ruled out a serious injury, his availability for Barcelona's next fixture remained uncertain as he attempted to regain his fitness.
According to Diario AS, Raphinha underwent a fitness test on Friday in the hope of being ready to face Getafe. However, the forward's physical condition during the assessment was not promising, and he subsequently missed the team's training session.
Barcelona have now been dealt an unwanted setback as Hansi Flick oversees preparations for the remainder of the campaign.
The Catalan side have returned to training following the first international break of the 2026–27 season, with their attention turning towards Getafe and a subsequent meeting with Galatasaray.
Raphinha will use the additional week to focus on his recovery, with Barcelona keen to have him available for more demanding encounters against Paris Saint-Germain and Real Madrid.
His absence will be keenly felt, particularly given his impressive form since moving into the centre-forward role.
The Brazilian has registered 14 goals in eight games and established himself as an influential figure in the dressing room, leaving Flick without both a prolific attacking option and an important leader.
