Orlando (Florida): Leander Paes, one of the world's best doubles tennis players, is being treated for a brain lesion and will miss the upcoming US Open.

Paes, 30, suffered severe headaches during his last match, a first-round loss on August 14 at the ATP Western and Southern Financial Group Masters in Mason, Ohio.

He checked himself into an emergency room near his Orlando home three days later, and a scan showed a lesion in the left occipital region of the brain.

He was transferred to MD Anderson Cancer Center in Orlando on August 19, hospital spokesperson said.

Tests are being conducted to determine the lesion's cause, with the results expected within a few days. A brain tumour has not been ruled out, the spokesperson said.

He is alert and speaking.
