PGA Tour star Tiger Woods announced Wednesday that he underwent another surgery on his right leg, which was severely injured in a car crash just outside of Los Angeles in 2021.

Woods said in a statement that he underwent a subtalar fusion procedure on his right ankle "to address his post-traumatic arthritis from his previous talus fracture."

The surgery was declared to be successful by Dr. Martin O'Malley of the HSS Sports Medicine Institute in New York City.

Woods did not give a timetable for his return.

Woods was involved in a single-car rollover crash on Feb. 23, 2021, and suffered serious injuries to his right leg. He underwent emergency surgery for fractures to his tibia and fibula and had rods, pins and screws inserted into his leg, ankle and foot.

The 47-year-old later revealed that he nearly lost his right leg.

After a lengthy recovery, Woods returned to the golf course for the first time in December 2021, taking part in the PNC Championship at the Ritz-Carlton Golf Club in Orlando, Florida, with his son, Charlie.

The five-time Masters champion made his return to the PGA Tour at the Masters Tournament in April 2022, finishing 47th. He then appeared in the PGA Championship in May 2022 but withdrew after the third round.

Woods then missed the 2022 U.S. Open that June, and in July 2022, he missed the cut at The Open Championship at St. Andrews., which was his final tournament of the 2021-22 season.

Woods has appeared in two tournaments this season, tying for 45th at the Genesis Invitational in February and withdrawing from the 2023 Masters Tournament in the third round with plantar fasciitis, which originally caused him to miss the Hero World Challenge in December.

While there has been no timeline given for Woods' return, there will be doubts about whether he can compete in the remaining majors this season. The second major of the year, the PGA Championship, is just one month away, and the U.S. Open is coming up in June.
