Tiger Woods revealed that he is planning to take a long break to rest his ailing back, which has been bothering him over the past five months.

In an interview during a Nike event on Monday, Woods confirmed that he will be out for a month or two, saying that he needs to recover fully from the back injury.

"It's probably going to be a month or two," Woods said of his lengthy break via ESPN. "I just need to get strong. It's one of the things that when I took that fall at Firestone No. 2, I hadn't done any agility work, so that's part of the deal."

Woods, who underwent back surgery in March to treat a pinched nerve, was forced to withdraw from the final round of the WGC-Bridgestone Invitational on Aug. 3 after falling into a bunker, sustaining another back injury that is unrelated to the injury he suffered earlier this year.

The 38-year-old golf superstar managed to participate in the 2014 PGA Championship, but was clearly out of sync as he failed to make the cut -- only the fourth time that he missed the cut in a major tournament.

Following his early exit in the PGA Championship, Woods announced on his official website that he will face a lengthy spell on the sidelines as ordered by his doctors.

"I've been told by my doctors and trainer that my back muscles need to be rehabilitated and healed. They've advised me not to play or practice now. I was fortunate that my recent back injury was not related to my surgery and was muscular only," Woods said.

Woods was also forced to withdraw his name from consideration for the U.S. Ryder Cup team, saying that he will not be ready to compete until the World Challenge.

"I plan to return to competition at my World Challenge tournament at Isleworth in Orlando, Florida, Dec. 1-7. It's an event that's important to me and my foundation, and it will be exciting to be playing again," Woods added.
