Elton John's spokesman says the singer has been hospitalized after suffering from a case of E. coli bacterial infection and the flu.
Gary Farrow said Monday that the pop star hopes to be released soon but has been forced to cancel concerts in England, Ireland and the United States.
John intends to rejoin the "Face2Face" tour later in the month when he and Billy Joel play concerts in northern California.
Farrow said 62-year-old John is suffering from a "bad case of the flu and a minor case of E. coli." His Web site says he was advised by his doctor to postpone dates in Seattle and Portland.
Farrow says the singer has rescheduled previously canceled dates during the European leg of his world tour.
