Tobi Amusan, the world women's 100m hurdles champion and record holder, is missing from Team Nigeria's list of 26 athletes for the World Athletics Championships in Budapest, Hungary. The list includes 11 male and 15 female athletes, with Ese Brume, Ruth Usoro, Sade Olatoye, and Chioma Onyekwere among the prominent females. The list also includes national champion Usheoritshe Itshekiri, Favour Ashe, Seye Ogunlewe, Alaba Akintola, Fakorede Adekalu, and Anunagba Karlington. Amusan's participation at the championship has been uncertain due to her provisional suspension by the Athletics Integrity Unit for missing three drug tests this season. The Athletics Integrity Unit has stated that there will be a hearing on her case before the World Championships, but nothing has been heard about the proceedings. Amusan made history at the championships last year, racing to a new world record time of 12.12secs in the semi-finals and 12.06secs in the final to clinch the gold medal.
