The sources have reported that the two parties have agreed for the bout to be staged in Lopez's native Mexico, at the famous Arena Coliseo in México City.
For Taconing the bout will see him get a long over-due second crack at a world title, and comes more than 4 years after his highly controversial loss to Kompayak Porpramook, in a bout for the very same title. Since that loss to Porpramook we've seen Taconing go 9-0 (8), and actually seen him make his Mexican debut, battering Ramon Garcia Hirales to a 10th round stoppage last year.
As for Lopez the bout will be his first world title defense and comes in the wake of his impressive win in Japan against Yu Kimura, who was himself making the first defense of the title. A win for the champion would cement his standing as a top Light Flyweight though he will likely be fully aware that Taconing is a vicious, heavy handed, and aggressive fighter who is a real handful.
Whilst we are awaiting for the bout to be officially confirmed we have heard that that announcement will be days away!
