Jordan Spieth has been disqualified at the Genesis Invitational in the Pacific Palisades, California.

Spieth, after shooting a 2-over 73 Friday, was DQ'd after he signed an incorrect scorecard.

Spieth signed for a 3 after making a 4 on the 245-yard, par-3 fourth hole, the PGA Tour said. He hit his tee shot into the left rough, chipped to within four feet and then missed the par putt.

The Texan opened the PGA Tour's third signature event of the year with a 5-under 66 on Thursday, placing himself firmly in the mix. However, after a disappointing showing on Day 2, was tied for 20th and 10 back of leader Patrick Cantlay.

Shortly after the DQ, Spieth posted a message on social media, saying “I take full responsibility.”

"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. Rules are rules, and I take full responsibility," Spieth wrote. "I love this tournament and golf course as much as any on (the) PGA Tour so it hurts to not have a run at the weekend. Really appreciated the support in LA."

Earlier in the day, tournament host Tiger Woods withdrew from the tournament due to sickness.

Spieth, who last won at the 2022 RBC Heritage, finished tied for sixth at the WM Phoenix Open last week.
