AKRON, Ohio — The PGA Tour rebutted a published report Friday that Dustin Johnson has been suspended for failing a drug test.

Johnson said in a vague statement issued by his management company that he would take a leave of absence effective immediately to seek professional help for “personal challenges.” The announcement Thursday brought an abrupt end to his PGA Tour season, knocking him out of the PGA Championship and the Ryder Cup.

Golf.com reported Friday that the tour suspended Johnson for six months. It cited an unidentified source as saying Johnson failed a drug test for the third time.

“With regards to media reports that Dustin Johnson has been suspended by the PGA Tour, this is to clarify that Mr. Johnson has taken a voluntary leave of absence and is not under a suspension from the PGA Tour,” the tour’s statement said.

It was rare for the tour to comment on any matters related to potential discipline. On Thursday, after Johnson announced his leave of absence, the only statement from the tour was that it had “nothing to add” and that it wished him well and looked forward to his return.
