Tiger Woods is undergoing surgery after he was involved in a single-car crash on Tuesday (Feb. 23) morning.

As TMZ reported, members of the Los Angeles Sheriff Department responded to “a single vehicle roll-over traffic collision” in L.A. County. The car, officials said, “was traveling northbound on Hawthorne Boulevard, at Blackhorse Road, when it crashed” and “sustained major damage.”

Responders confirmed Woods was the driver, noting he was “extricated from the wreck with the ‘jaws of life’” before he was transported to local hospital. He sustained multiple leg injuries as a result of the accident and is currently in surgery, per his agent, Mark Steinberg.

It is not yet clear what led to the accident, but a law enforcement source told TMZ that alcohol doesn’t seem to be involved. An investigation is underway to determine the actual cause of the collision.

Woods, Golf Digest reported, was in the Pacific Palisades over the weekend for his annual PGA Tour’s Genesis Invitational, where he served as the event’s host. He remained in California for a two-day shoot with Golf Digest/GOLFTV that would capture him “giving on-course lessons to a number of celebrities.” On Monday (Feb. 22) — the first day of the shoot — he posed with the likes of Dwayne Wade and David Spade at Rolling Hills Country Club, but his movement appeared to be restricted as he “mostly provided instruction” and failed to hit any balls or play any holes.

Woods recently underwent a microdiscectomy procedure — his fifth back surgery — to remove a disc fragment that was pinching a nerve. He told CBS that the results of an upcoming MRI would determine whether he was ready to resume training and prepare for his return to golf.

Woods’ two-day shoot with Golf Digest/GOLFTV was supposed to end today (Feb. 23), but under the circumstances, he was unable to finish filming.
