Rory McIlroy's lack of appreciation for the Olympics is unacceptable and golf's place should be reconsidered, says squash player Laura Massaro.
McIlroy is among several top players who will not attend Rio, where golf returns to the Games after 112 years.
He says he never "aspired to" compete, while former world squash champion Massaro insists her sport would consider the Olympics as its pinnacle.
"It's frustrating," she said. "There are athletes who would really want it."
Squash has consistently missed out on a place in the Olympics - including in 2009 when golf was voted in.
Massaro told BBC radio 5 live: "I think part of being a professional athlete is also to grow the game and be a role model for young people watching on TV, and the Olympics is the perfect opportunity to do that."
McIlroy: I don't feel I've let golf down
The top four men's golfers in the world, including McIlroy, have now all pulled out of next month's Olympics citing health concerns, but 32-year-old Massaro does not believe any squash players would have withdrawn.
Italy's Francesco Molinari has also pulled out because of family reasons, bringing the number of men's players who have decided not to compete to 20.
"With a lot of the golfers blaming the Zika virus it's hard to know whether or not that's true," added Massaro.
Northern Irishman McIlroy, 27, said golf is "all about the four majors" and "that's the way it should stay", but that he would consider competing at Tokyo in 2020.
However, the International Olympic Committee (IOC) will make a decision on which sports will compete in the 2024 Games before Tokyo takes place.
