The Netherlands international picked up the injury during Barcelona's training session ahead of their La Liga clash with Villarreal. Initial tests suggest a possible muscle tear that could keep him sidelined for up to four weeks.
De Jong's absence comes at a crucial time as Barcelona had nearly a full squad available. He will miss key matches including the Copa del Rey semi-final second leg against Atletico Madrid, the Champions Round of 16, and several La Liga fixtures. Manager Hansi Flick will now need to rely on midfielders like Marc Bernal, Marc Casado, or even Eric García to partner with Pedri.
