Tottenham striker Emmanuel Adebayor is suffering from malaria and will miss the pre-season tour of North America, the club have announced.
The Togo international was admitted to hospital on Saturday after feeling unwell and was diagnosed with a mild bout of the disease.
The club said the illness was detected at an early stage and Adebayor was responding well to treatment.
He is expected to be released from hospital on Monday and will then require a minimum of seven days before returning to training.
He has been advised not to travel on medical grounds and so will miss the club's pre-season tour.
The 30-year-old enjoyed a fine season last term after Tim Sherwood replaced Andre Villas-Boas as boss and will be hoping to impress the new man at the helm, Mauricio Pochettino.
