PRAGUE—Zuzana Hejnova, a two-time world champion in the 400-meter hurdles, won’t compete in the Tokyo Olympics due to an Achilles tendon injury, she said Thursday.

Hejnova’s back and Achilles problems prevented her from competing this season and she won’t fully recover for the Tokyo Games, which open in eight days.
