Tiger Woods recently underwent back surgery after experiencing discomfort at the PNC Championship and will miss the Farmers Insurance Open and the Genesis Invitational, he announced Tuesday.

Woods, 45, had a microdiscectomy procedure to remove a pressurized disc fragment that was pinching a nerve in his back. The timeline for his return to the PGA Tour is unknown, but he's expected to make a full recovery.

"I look forward to begin training and am focused on getting back out on Tour," Tiger said.

Woods, who played in the PNC Championship with his son Charlie, was spotted wincing on the range at the December tournament.

The operation is Tiger's fifth for his back and first since he underwent a spinal fusion in 2017. That procedure allowed him to return to the PGA Tour and win three events, including the 2019 Masters.

Though he will not compete at Riviera, Woods will still be at the Genesis Invitational as the tournament host. Proceeds from the event benefit his TGR Foundation.
