"I can go and hope to start training again in the next few weeks," says Woods, who has set his sights on a comeback in Japan October 24-27, reports Reuters.
Three weeks ago, Woods jumped from a PGA competition in New Jersey after the first round's 75 strokes with reference to "pain and stiffness" without specifying in more detail.
As recently as a week ago, Woods said he would take out the December Presidents Cup team without mentioning the operation and its consequences.
Woods made an incomparable comeback and won the Major the Masters earlier this year but apart from that hit has had a mediocre season but is ranked eighth in the world.
Woods has undergone four back surgeries in seven years. The large number of surgeries and recurring injury problems impede American mobility.
