Tiger Woods out of Genesis Invitational due to illness as Jordan Spieth is disqualified

Woods, tournament host this week, returned to the PGA Tour on Thursday, finishing his opening round at the Riviera Country Club on one-over par.

But the American could not back that up a day later as he withdrew after six holes due to illness.

Rob McNamara, executive vice president of TGR Ventures, told PGATour.com Woods had started feeling flu-like symptoms on Thursday night.

"He had a little bit of a fever and was better during the warm-up, but then when he got out there and was walking and playing, he started feeling dizzy," McNamara said.

"Ultimately the doctors are saying he's got some – potentially some type of flu and that he was dehydrated. He's been treated with an IV bag and he's doing much, much better and he'll be released on his own here soon."

Woods is still adapting to ankle fusion surgery, having undergone treatment in April last year after withdrawing from the Masters during the third round and he did not compete again until the Hero World Challenge in December.

He had suffered from a back spasm towards the end of his first round, shanking his second shot on the 18th from the fairway over into the trees on the right, eventually sinking a two-putt bogey to make a five.

Woods started in fine form on Friday, producing a birdie on the first, but back-to-back bogeys arrived from the fourth and he called it a day after a third par on the sixth left him one over for his round.

He was driven back to the locker room by a rules official.

Following Friday's play, it was also announced that Jordan Spieth was disqualified for signing for an incorrect scorecard.

In a statement on X, the PGA Tour said: "Jordan Spieth has been disqualified from The Genesis Invitational for signing for an incorrect scorecard.

"Spieth signed for a 3 and made a 4 on No. 4."

Spieth took to X afterwards to accept responsiblity for the error.

"Today, I signed for an incorrect scorecard and stepped out of the scoring area, after thinking I went through all procedures to make sure it was correct," Spieth wrote on X on Friday night. "Rules are rules, and I take full responsibility. I love this tournament and golf course as much as any on @PGATOUR so it hurts to not have a run at the weekend. Really appreciated the support in LA."

American Patrick Cantlay takes a five-shot lead into the weekend at 13 under, with the trio of Luke List, Jason Day and Mackenzie Hughes his nearest challengers on eight under.

Rory McIlroy fought superbly to beat the cut by following up Thursday's disappointing 74 with a superb 66.
