Legendary golfer Tiger Woods has thanked people for their support after saying he had completed an "intensive" programme to help him manage medication for back pain and a sleep disorder.

Woods gave little information on the programme when he announced in a tweet in June that he was "receiving professional help to manage my medications and the ways that I deal with back pain and a sleep disorder". His longtime manager later said that the golfer had "checked himself into a facility".

The announcement came on the back of the former world number one's arrest in Florida where police said he was found asleep at the wheel of his car beside the road. Dashcam footage showed Woods stumbling and slurring while police arrested him.

Woods said that the incident involved an adverse reaction to prescription medications and court documents showed that a breathalyser said he had not been drinking. Woods has undergone a number of surgeries and struggled with injuries that have left him unable to compete.

"I recently completed an out of state private intensive programme," Woods wrote in a statement on Twitter, adding: "I will continue to tackle this going forward with my doctors, family and friends.

"I am so very thankful for all of the support I've received." Woods said.
