Dustin Johnson is one of the top golfers in the world and he now will be suspended from the sport for six months, as reports from Golf.com have Johnson failing a drug test and testing positive for using cocaine and this comes after he previously was suspended in the past for a drug test failure and now the fiance of Paulina Gretzky will be off the course for a while.

According to Golf.com, Johnson was suspended for a positive drug test regarding cocaine use and he has now been hit three times in his career. Sources say the suspension came for another failed test and this comes after he previously failed tests for marijuana and also for cocaine once before and that was two years ago. Before the new broke about the cocaine test, Johnson announced that he was taking a leave of absence from golf.

The suspension comes as the 30 year old was getting ready for the PGA Championship and the Ryder Cup and that means he will miss both. Johnson now also will miss out on the FedEx Cup playoff series and this comes as he is one of the most promising US golfers for the American Ryder team.

Johnson is engaged to Gretzky and they announced their news last year and now Johnson has another suspension. Back in 2012, Johnson's test failure was not made public and while he was out for 11 weeks, he said that he was injured, but sources say he was suspended during that time.  

Johnson said through his management agency: "I will use this time to seek professional help for personal challenges I have faced," he said in a statement issued by his management company. "By committing the time and resources necessary to improve my mental health, physical well-being and emotional foundation, I am confident that I will be better equipped to fulfill my potential and become a consistent champion."
