Ciara Mageean: Brendan O’Sullivan case exposes naivety of GAA

International athlete Ciara Mageean has challenged Sport Ireland’s claim that Kerry footballer Brendan O’Sullivan bore “no significant fault” following his positive test for methylhexaneamine last year.

“For an athlete to be like: ‘oh, I didn’t know’, it doesn’t wash with me,” said Mageean.

“Maybe there is a naivety in the GAA where the athletes aren’t aware [of what they are taking], but that’s the responsibility of the GAA to educate their athletes and for athletes to educate themselves.”
