Spain striker Dani Olmo will miss Sunday's UEFA Nations League match against Switzerland and return to Barcelona early with a minor knee problem.
Olmo, 26, came off the pitch in the 82nd minute of the European champions' goalless draw with Serbia in Belgrade on Thursday.
Sources insist the injury is not serious but it has been decided that it is best for him to sit out the game against Switzerland and return to his club.
Barca, who have won all four of their league games this season, return to league action next Sunday at Girona and coach Hansi Flick hopes to be able to count on Olmo.
Olmo joined Barca this summer from RB Leipzig for 55 million euros ($61 million) but missed the first two games of the campaign because he was not registered due to the club's problems complying with La Liga's financial fair play rules.
He was eventually registered and made his debut in the 2-1 win over Rayo Vallecano, scoring the winning goal, and scored again in the 7-0 win over Real Valladolid before the international break.
Barca are thin on the ground in midfield, where Olmo has been used by Flick, with Gavi, Frenkie de Jong and Marc Bernal injured, while Oriol Romeu and Ilkay Gündogan left the club in the transfer window.
De Jong could return in the coming weeks while Gavi is in the final stages of his recovery from an anterior cruciate ligament injury that has sidelined him for almost a year, but Bernal is expected to miss the rest of the season.
Flick is also dealing with injury problems in defence, with centre-backs Ronald Araújo and Andreas Christensen out for the near future.
Moving forward, Ansu Fati is expected to be available after the international break and will add further depth to the attack after returning from a season-long loan at Premier League club Brighton.
