Knee injury forces Sergi Roberto off at half time against Eibar
Sergi Roberto was forced off with a knee problem at half time of Barcelona's match with Eibar on Saturday.
The academy graduate played the first 45 minutes at right-back before being replaced by Nelson Semedo at the break.
Subsequent medical tests will determine whether he will be fit to play Slavia Prague in the Champions League on Wednesday.
He has played in 10 of Barcelona's 11 games so far this season, with the home win over Valencia in September the only match he has missed.
