Tiger Woods made a rare public appearance at the US Open to watch Rafael Nadal

Tiger Woods has been relatively quiet since his latest back surgery in April and his arrest in May, but he made a public appearance on Friday at the U.S. Open.

Woods appeared to be sitting alone in Arthur Ashe Stadium during the semifinal match between fellow Nike athletes Rafael Nadal and Juan Martín del Potro. Woods was wearing a Tiger Woods branded cap and an Oakland Raiders jacket.

After Woods’ arrest, he announced that he was receiving “professional help to manage” his pain medications. It was reported that he had five different drugs in his system at the time of his arrest. Woods eventually reached a plea deal in his case.

Woods announced in July that he had completed his program.
