Katie Taylor has revealed the biggest defeat of her life was the catalyst that launched her professional career - and without it she wouldn't be headlining Madison Square Garden tonight.
The Bray fighter defends her lightweight belts against Amanda Serrano at the Mecca of boxing, with over 20,000 fans expected to be in attendance, but it could have been a much different story for Ireland's golden girl.
Four years after winning gold at the London Olympics, Taylor suffered a shock loss to Finland’s Mira Potkonen at the 2016 Games in Rio.
