Novak Djokovic has pulled out of the Cincinnati Open for what officially was listed as a “non-medical” reason. Monday's withdrawal means he will head to the U.S.

Djokovic, ranked No. 6 in the world, is bidding to win a record 25th major at the U.S. Open, which begins Aug. 24. He lost to world No. 1 Jannik Sinner in the semifinals at both Roland Garros and Wimbledon. The Cincinnati Open is still headlined by Sinner and Alcaraz, with many other top stars playing.

Novak Djokovic will no longer compete in the Cincinnati Open this weekend after withdrawing for a "non-medical" reason, per the Associated Press (h/t ESPN).
