Australian golfer Jason Day has withdrawn from the 2024 US Open due to a back injury sustained during his second round. The former champion was visibly in discomfort and ultimately required a golf cart to leave the course. Day, who won the US Open in 2015, had been struggling with his swing prior to the injury. His withdrawal marks a disappointing end to his campaign at Pinehurst No. 2. Details regarding the severity of the injury have not yet been released. This is a setback for Day, who was hoping to contend for another major championship title.
