The Spain international sat out Barca's training session on the eve of the derby at Espanyol due to soreness in his right adductor
Barcelona captain Andres Iniesta missed training due to injury ahead of Saturday's derby showdown with Espanyol.
Luis Enrique's men face their neighbours at Estadi Cornella-El Prat but could be without Iniesta after the 32-year-old sat out Friday's session with a right adductor problem.
Teenage midfielder Carles Alena trained with the first-team in Iniesta's absence.
Barcelona returned to the top of LaLiga by virtue of a superior head-to-head record over Real Madrid following last weekend's dramatic 3-2 Clasico win at the Santiago Bernabeu.
