The qualifiers, which begin on Sunday in Caracas, Venezuela, was open to professional fighters and it appears that Ruenroeng may well be the biggest name professional to sign up to the competition, which would allow him to compete for Thailand in the Olympics.
The former champion will be returning to the ring for first time following his title loss earlier this year to John Riel Casimero. Although that loss was a bad one we didn't expect Ruenroeng to look towards the Olympics for his future success.
Whilst Amnat signing up to the Olympic qualifier was a slight shock it's more revealing that the sources have reported that the Thai, who fought at 112lbs in the professional ranks, will be fighting at 60KG's at the amateurs, which is over 132lbs. The move up in weight was a major surprise and although we do know Amnat has been struggling at 112lbs this does seem a bizarrely big move up considering his frame and style.
