In-form forward Lionel Messi is a doubt for Barcelona's La Liga match at Real Zaragoza on Sunday after missing training with a tooth abcess.
Coach Pep Guardiola included him in the squad on Saturday but said: "He's gone home and we'll see how he is tomorrow. He was in a lot of pain."
The Argentina international has scored eight goals in Barcelona's last four matches in all competitions.
Meanwhile, Valencia defender Carlos Marchena has been ruled out for three weeks with a torn thigh muscle.
The experienced Spanish international is set to miss the Europa League quarter-final against Atletico Madrid next month.
