Reigning World 100m hurdles champion and record holder (12.12), Tobi Amusan may open her Diamond League campaign at the Athletissima in Lausanne, Switzerland on June 30, 2023 after missing the opening leg of the money spinning competition in Doha last Friday.
The Nigerian, 26, is the defending Diamond League champion in the high hurdles and will likely return to the venue for the second straight year.
Amusan ran 12.45 last August to place second behind reigning Olympic champion, Jasmine Camacho-Quinn who ran 12.34 to win.
The Nigeria, African and Commonwealth Games champion opened her 2023 outdoor campaign in April at the Tom Jones Memorial in Gainesville, Florida where she ran 12.74 in the heat and 12.59 in the final where she finished second.
She is currently the seventh fastest in the event so far this year.
Meanwhile, World indoor and outdoor championships silver medalist, Ese Brume may start her 2023 Diamond League campaign at the Golden Gala in Rome/Florence.
Brume started her outdoor campaign with a 6.77m leap at the Botswana Grand Prix at the end of April to rank third in the 2023 top list.
The 27 year old will be seeking to make it to the Diamond League final this term and win the long jump title after missing out last year with just two points.
Brume will be the first Nigerian to compete at the Golden Gala since Tobi Amusan ran 12.86 to place third behind USA’s Sharika Nelvis (12.76) and Williams Daniel of Jamaica (12.82) in May 2018.
Charity Opara, the 1996 Olympic 4x400m silver medalist ran a spectacular 49.29 to set a lifetime best at the meeting in July 1998 ahead of compatriot, Falilat Ogunkoya who finished third in 49.89.
