Tyrrell Hatton withdrew from the Valspar Championship on Tuesday after testing positive for COVID-19, the PGA TOUR announced.
The Englishman is the fourth player to pull out of the Tampa event with a positive test result. Sepp Straka, Will Gordon, and Brice Garnett withdrew earlier in the week.
Hatton was one of four top-10 players in the world competing at the Valspar Championship. Dustin Johnson, Justin Thomas, and Patrick Reed are the other three.
He'll be replaced by Kiradech Aphibarnrat.
