Toru Taniguchi, last season's top golfer on the Japanese men's circuit, has pulled out of this week's Memorial Tournament on the U.S. PGA tour due to illness, his management company said Wednesday.

Taniguchi was scheduled to appear at the May 29-June 1 tournament in Columbus, Ohio, but has withdrawn after coming down with a high fever and is expected to also sit out next week's FBR Capital Open.

Taniguchi missed three U.S. PGA Tour events earlier this year because of illness.

He was hospitalized in February after being diagnosed with angioma, a tumor composed mainly of lymph and blood vessels, which can cause loss of tissue and structural weakening of the bones.
