Ronald Araujo is expected to be out for at least six weeks after picking up a muscular injury playing for Uruguay against Brazil at the Copa America.
The defender went off early and looked pretty upset as he departed the match which Uruguay went on to win in a penalty shoot-out.
Early estimates claim Araujo faces at least six weeks on the sidelines, although we may get more of an idea of the severity of his injury when he undergoes further scans.
However, the initial outlook is not too optimistic which will be a real blow to Barcelona ahead of the new La Liga season.
