New York: Grand Slam champion Leander Paes, who has been detected having a cyst in the brain, was in a stable condition, the doctor attending on the Indian tennis star in an Orlando hospital said.

"Paes is stable. We are testing mainly for bacterial infection," Clarence Brown, the president chairman of the MD Anderson Cancer Centre, said on August 20.

The 30-year old Paes first checked himself into an emergency facility near his Orlando home on August 17 after experiencing severe headache for three days.

Tests revealed a lesion in left occipital region of the brain and he was subsequently moved to MD Anderson Hospital.

Brown refused to make any further comments but did not rule out the possibility of a tumour.

"It would not be proper to make any comments before the results are known, but a tumour is not ruled out," he said.

Brown said the results would be known in the next 24 hours.
