Travis Kelce and the Kansas City Chiefs have the weekend off after beating the Baltimore Ravens in the NFL's season opener Thursday night at Arrowhead, so the star tight end was able to check out a different sport on Sunday.

Kelce and his girlfriend, pop star Taylor Swift, are at the U.S. Open in New York where Jannik Sinner and Taylor Fritz are battling in the men's championship match.
