(SportsNetwork.com) - Dustin Johnson announced on Thursday that he is taking a leave of absence from the PGA Tour.

Johnson, an eight-time winner on the PGA Tour, released a statement to media outlets that read in part, "I am taking a leave of absence from professional golf, effective immediately. I will use this time to seek professional help for personal challenges I have faced.

"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."

The 30-year-old had withdrawn from the WGC-Bridgestone Invitational earlier in the week. The PGA of America announced that Johnson will not take part in next week's PGA Championship or the Ryder Cup in late September.

Johnson is fifth on the United States Ryder Cup points list. With him not playing the event, that means whoever is ranked 10th on the points list as of Monday, August 11, will make the team automatically.

The PGA Tour released a brief statement that read, "We have nothing to add to Dustin's statement. But wish him well and look forward to his return to the PGA Tour in the future."
