Phil Healy failed to progress from her heat of the women's 200m at the Athletics World Championship.
She finished fifth of six competitors in the first heat in Doha in a time of 23.56, well outside her season's best of 23.04.
The Cork sprinter, with a 22.99 PB, suffered a hairline fracture in her foot earlier this year and that hampered her preparation for the championships.
Her race was won by Anthonique Strachan of the Bahamas in 22.66, with Kamaria Durant from Trinidad & Tobago and Jamaica’s Shashalee Forbes taking the two other automatic qualifying times.
Speaking afterwards to RTÉ Sport, Healy said: "I did expect a bigger time than the 23.5 so in that way I'm disappointed but am I lucky to be here? 100% yes.
"It has been a long season, it has been a hard season and I'm just grateful that I can run this season and come to the World Champs.
"I'm really lucky to be competing this season. Breaking your foot isn't the ideal preparation, that happened at the end of April and that knocked everything on it's head for the season and I was lucky to come back.
"As any other athlete knows once you break the momentum it's hard to get back to the place where you were beforehand but I am happy to be here and competing with the world's best."

Defending champions Dafne Schippers pulled out of Healy's heat due to an injury that she suffered in her 100m semi-final, which also forced her to miss the final in the shorter distance.
