Barça midfielder Malcom scored a goal in tonight’s encounter with Cultural Leonesa but was unable to finish the match due to a sprained right ankle.
The Brazilian will be examined more thoroughly on Thursday to determine the full extent of the injury.
It was a stroke of misfortune that led the player to slip nastily. He left the field in tears and to a standing ovation from the over 76,000 fans in the stadium.
With all three substitutions made, Barça saw out the remaining moments with just ten men, although by then the place in the last sixteen of the Copa del Rey was more than secure.
