Tiger Woods has suffered a setback with his back, disclosing Tuesday that he recently had a fifth surgery that will keep him from starting the year until after the West Coast Swing on the PGA Tour.

Woods will not play next week in the Farmers Insurance Open at Torrey Pines, which he has won seven times, most recently in 2013. He also won the U.S. Open in 2008 at Torrey Pines, which hosts the U.S. Open again in June.

He also will miss the Genesis Invitational on Feb. 18-21 at Riviera, where he serves as tournament host.

In a statement from his TGR Foundation, which Woods also tweeted, he did not say when he had the microdiscectomy surgery though Rory McIlroy, speaking Wednesday at a news conference ahead of the Abu Dhabi Championship, said it took place on Dec. 23 and that Woods was “back on his feet the next day.”

It was to remove a pressurized disc fragment that was giving him nerve pain during the PNC Championship last month that he played with 11-year-old son Charlie.

Doctors said the operation was a success and predicted a full recovery, according to the statement.
