Rory McIlroy had to switch drivers at the PGA Championship after his gamer was deemed non-conforming, according to a report by PGA Tour radio’s Jason Sobel. McIlroy is known as the best driver of the golf ball of his generation.

The Masters champion had his regular driver deemed non-conforming Tuesday and had to put a backup in play at Quail Hollow.

The 2025 PGA Championship has arrived with three days of pristine golf remaining at one of the United States' most notable courses. A massive field featuring 99 of the top 100 golfers will tee it up at Quail Hollow again Friday with 54 holes remaining until the Wanamaker Trophy is awarded to this year's champion.
