Double European silver medallist Derval O'Rourke has pulled out of this weekend's Woodies DIY National Indoor Championships in Belfast due to a groin niggle.
But her coach Sean Cahill has stressed it is merely a precaution to avoid any problems ahead of next month's European Indoor Championships in Paris.
O'Rourke ran a season's best of 8.03 seconds in France last week but pulled out of a subsequent race in Germany because of a slight tightness in her groin. She was expected to be back out racing, both in Birmingham and Belfast, this weekend, but will remain in training instead.
Fellow Irish sprinter Claire Brady (Celbridge AC), who will be defending her Irish 60m title in Belfast, was boosted yesterday by signing a sponsorship deal with ESB Electric Ireland.
Meanwhile, Kevin Dooney of CBC Monkstown won the boys' senior race at the Aviva Leinster Schools Cross Country Championships in Santry yesterday.
Dooney took the lead on the opening lap of the 6,000m race, with national U-19 champion Liam Brady of St Brendan's, Birr doing his best to stick with him.
By the third lap, Dooney was pulling away and came home a comfortable winner.
Maire Aine Ni Shuilleabhain, of Gaelcholaiste Cheatharlach, beat her old rival Mary Mulhare of Presentation Portlaoise to win the girls' senior race.
In the girls' inter race, eventual winner Siofra Cleirigh Buttner, of Colaiste Iosagain, was already ahead after the opening 50 metres.
She also led her school to one of three team titles on the day.
