Jon Rahm has withdrawn from the 2023 Players Championship.

The No. 1 player in the world was announced as a late WD ahead of his second round tee time Friday at TPC Sawgrass. The PGA Tour announced that Rahm dropped out due to an unspecified stomach illness.

Rahm was part of the super-pairing with Rory McIlroy and Scottie Scheffler. Rahm turned in an uneven performance on Thursday but still managed to post a one-under 71.

Rahm had entered TPC Sawgrass on a heater, winning three times and finishing T-7 or better in six of seven starts this season. He is ranked first on the PGA Tour in strokes gained/total and scoring. A victory this week would have given Rahm the most wins this early in a tour year since Jack Burke, Jr. in 1952.

It is unlikely that Rahm will play in next week’s Valspar Championship. Rahm’s next scheduled appearance will come at the WGC-Dell Match Play in two weeks.
