AKRON, Ohio (AP) -- 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.
The PGA Tour began drug testing in July 2008.
One year later, PGA Tour Commissioner Tim Finchem was asked to confirm that there had been no positive tests in the first year from either recreational or performance-enhancing drugs. He drew a distinction between the two.
''I said we have had no positive tests with respect to performance enhancing. We may have had some test results that trouble us in other areas that we treat in a different bucket,'' Finchem said in July 2009. ''But we don't publicize those. We treat those as conduct unbecoming. If we get a test like that, we will consider it conduct becoming, and what are our choices? We can suspend a player. We can fine a player. We can do both of those and put a player into treatment.''
Johnson is not the first player to take a leave of absence.
John Daly announced in September 1994 that he was taking the rest of the year off because of ''mental and physical'' problems. In announcing Daly's decision, Finchem repeatedly used the word ''voluntary,'' but said the decision was reached after numerous meetings between Daly and the tour.
Daly said Friday evening he could not recall details from 20 years ago. He said of Johnson, ''I hope he's all right.''
Daly most recently was suspended in 2008 following a tumultuous year of off-course incidents. He called The Associated Press to say he had been suspended for six months because ''I'd rather be honest, especially with the fans.''
The tour, told that Daly had confirmed his suspension, declined comment citing its longstanding policy on not discussing discipline.
Meanwhile, the PGA of America issued a new Ryder Cup points list Friday that removed Johnson from the standings. He had been No. 5, virtually certain to be an automatic selection when qualifying ends after the PGA Championship next week.
