Eileen O'Keeffe will not take part in this weekend's Morton Memorial Meeting in Santry after picking up a minor knee injury last weekend.
The problem, sustained at the national track and field championships, has raised doubts over the hammer thrower's availability for the forthcoming Olympic Games in Beijing.
However, while a scan has revealed inflammation around O'Keeffe's left knee, Irish team manager Patsy McGonagle remains confident the Kilkenny City Harriers athlete will be fit for China.
"The Athletics Ireland medical team are working with Eileen to ensure that she has a full recovery and will be ready in time for Beijing," he said today.
David Gillick, meanwhile, is back in training following the knee problem that sidelined him over the weekend.
"I just had a bit of a niggle in my right knee and that's why I didn't run over the weekend, I just wanted to be cautious about it," he explained.
"I'm quite confident that everything is okay and it hasn't inhibited me much in training or races recently.
"Just because I was at home in Dublin I said that I might as well get a scan on it and get it checked out to make sure everything was okay."
The two-time European Indoor champion has been relatively injury-free in recent years and should be in peak condition for the Irish team's pre-Games holding camp, which they begin departing for on Friday week.
"I've had a couple of small niggles (before), but nothing too major," Gillick said. "In 2005 I had a back problem that ruled me out of the World Championships.
"But at that time I was young and I didn't know how to take it after winning the European Indoor Championships in Madrid and then carrying the injury through the season.
"Thankfully, since then, everything has been going all right for me."
