Samuel Umtiti will return to Barcelona on December 30 for further "conservative treatment" on his knee after undergoing therapy in Qatar.
The France international last featured for Barca almost a month ago in Barca's 1-1 draw at Atletico Madrid on November 24, but a persistent knee issue has troubled him ever since.
Umtiti had been having treatment with specialists in Qatar ever since the end of November.
He has played just seven times in La Liga this term, having also missed two months when the knee injury first flared up in September.
Barca have been severely impacted by injuries at centre-back this term, with Clement Lenglet and Gerard Pique the only fit senior players for the position in Saturday's 2-0 win over Celta Vigo.
