Katie Taylor admitted that a weight has been lifted from her shoulders after qualifying for her second successive Olympics in Kazakhstan yesterday.
The No 1 seed in the lightweight class at World Women's Elite Championships beat Mexico's Victoria Torres on a unanimous decision in a fiery quarter-final.
Yesterday's verdict guarantees the Olympic champion at least bronze and a sixth successive World podium finish.
"It's definitely a big weight off my shoulders, the Olympic Games have always been the most important thing for me," said Taylor. "It has always been a dream of mine since London 2012. This is every boxer's dream.
"Thursday is another big test and I will have to perform to my best to reach the final. It was a tough fight today against a tough opponent. Thank God I came through it."
Kellie Harrington is also assured of at least bronze. The Dubliner convincingly beat Kazakhstan's Zarina Tsoloyeva in the light-welter class.
In the wake of the controversy surrounding the selection of Ireland's Olympic Games marathon team, Athletics Ireland has rejected Sergiu Ciobanu's assertion that his background played a role in the decision.
