Thomas Vermaelen will miss Barcelona's final game of the season against Real Sociedad next weekend with a hamstring injury.
The centre-back was forced off just 30 minutes into Sunday's match at Levante, where an astonishing 5-4 defeat ended Barca's hopes of an unbeaten top-flight campaign at the penultimate hurdle.
Barcelona did not give a timeframe on Vermaelen's estimated return date following tests on Monday and his condition will be a concern for Belgium head coach Roberto Martinez.
The 32-year-old, who has battled numerous injury problems over recent years, featured in the Red Devils' successful World Cup qualifying campaign.
