Nathan Chen will go to the world championships to attempt to defend his title, U.S. Figure Skating announced on Sunday.
But he will not compete at the Four Continents Championships that begin Feb. 5 in Anaheim, Calif. Chen won Four Continents in 2017.
The two-time Grand Prix Final champion won his third consecutive national title earlier Sunday.
Chen will be joined by 2019 U.S. medalists Vincent Zhou (silver) and Jason Brown (bronze) at Worlds, held March 18-24 in Saitama, Japan.
Zhou, Brown, and pewter medalist (fourth place) Tomoki Hiwatashi will compete at Four Continents.
