Reports suggest that Napoli legend Diego Armando Maradona has returned to a Buenos Aires hospital.
The Argentine discharged himself from the clinic last week after spending 12 days in intensive care.
The 43-year-old was rushed to hospital after falling ill with heart and lung problems on April 18.
Now Argentine media reports allege that the 1986 World Cup winner is back in hospital after further problems.
The Suizo-Argentina clinic would not confirm that Maradona, widely regarded as one of the greatest players in the history of the game, had been admitted overnight.
Speculation on Monday suggested that Maradona was preparing to return to Cuba to resume treatment.
