Rhasidat Adeleke will miss this weekend's National Track and Field Championships in Santry.
The Dublin sprinter "continues to focus on recovery following recent race exertions" according to Athletics Ireland, with full focus on the upcoming World Championships in Tokyo.
Adeleke has recently raced in the Diamond League meetings in Oslo, where she was fourth in the 400m, and in London, where she was fourth in the 200m. The Tallaght athlete was also a late withdrawal from the 400m at the Diamond League in Monaco earlier this month.
The 22-year-old's season's best of 50.42secs is outside the top 20 in Europe, and is a significant drop-off from the Irish record she set in last year's European final.
Sharlene Mawdsley is set to face off against Olympic teammates Sophie Becker and Phil Healy while Sarah Healy and Sophie O'Sullivan headline the 800m. Sarah Lavin, Mark English, Israel Olatunde will all be involved across the weekend while the in-form Kate O'Connor and Nicola Tuthill will be in action in the field events.
Athletes who skip the nationals generally need dispensation from Athletics Ireland, who only grant exemptions for "medical reasons and/or exceptional circumstances".
