The details are scarce but from what we understand Go was unable to meet a mandatory defence date in Mexico.
Go's reign as champion began last year when she defeated Renata Szebeledi in May. She made 2 defences of the title, defeating Judith Rodriguez last December and Kledpetch KKP, then fighting as Kledpetch as Lookmuangkan, back in May this year.
It's a shame to see the 27 year old end her reign as champion like this though hopefully she'll return to the ring in the near future and attempt to reclaim her title somewhere down the line.
