Jordan Spieth started 297 career -pga tour.

On Thursday, he withdrew the mid-tournament for the first time.

Spieth injured his neck while warming up on the series before the opening round of the Travelers Championship. He chose to play through the injury and 5 through his first 12 holes.

But Spieth could be heard in noticeable pain after his tea shot on the Par-5 hole. And after his second shot from the left Fairway, he only got 16 feet from the ground before finding another bunker, Spieth told his Caddy, Michael Greller, “I’m done. Can’t do that. I’m sorry. ‘

Spieth then called an official of the rules uncertain about the protocol for withdrawal.

“How’s this job doing?” Spieth asked the official. “I’ve never done it.”

Spieth handed over his contestant, Luke Clanton, before jumping on a golf cart to return to the clubhouse, where he answered a few questions for reporters.

“It was just like halfway through my irons,” Spieth said when the injury occurred. “Everything was wonderful in my gym session, and I was very, very excited to play out. Things got better, and then my right just locked up a kind, like fasting halfway through the warm -up, and I just kept hitting, and then it suddenly came up … and then it was over the left and then it was like everything, so I stopped. It was both the neck and the upper back. ‘

He ended his warm -up about 30 minutes early, and Spieth headed straight to his physio, Marnus Marais, which also works on Scottie Scheffler and Justin Thomas, among others. He did not know how he sustained the injury, except to speculate that he was sleeping wrong.

“I would just try to see if I could even get through,” Spieth added. ‘This is a strange situation with an increased event and no cut and important points and things. It’s like, now, what’s the downside if I can just finish just ending, even if it’s ugly, and then I hit my tea shot at 13, and it has legally hurt. I walked off the tea, and I, if it is even harder to turn, I will not shot the stack. I was only worse to finish the round, and it’s not worth it.

“I’ve never withdrawn anywhere at any level, so I didn’t really know what to do. It just got too much. ‘

By withdrawing, Spieth will receive money in the limited field, signature event, but he will not receive FedExCup points.

Spieth, who missed the first month of the season while recovering from the left wrist operation last August, is currently the 37th place in points. He started four top 10s in 15 and came to the US Open last week from a T-23. It was his 10th tournament over the past 12 weeks.

He and his wife, Annie, expect their third child within the next few weeks.

“I will have some time to get healthy now, but hopefully after a few days I go through the right process of just getting back where I was,” Spieth said. “Yes, it’s a bummer. Of course, this is a bummer at this occasion. “
