It's rare to have unification bouts in the day and age, despite their being 4 world titles. It seems that pride has been lost by many modern day boxers who would rather hold a title rather than defend it and prove themselves.
Whilst unifications are rare enough it's even rarer to have unification bouts between two men from the same country. Thankfully however they do happen and when they do they are special, as we saw when Akira Yaegashi, then then WBA Minimumweight champion, battled compatriot Kazuto Ioka, then then WBC Minimumweight champion.
The bout, which took place in 2012 was an amazing contest that saw Ioka try and box and Yaegashi try to make the contest into a war, despite grotesque swelling over his eye. If you've not seen this before you've been missing out and really should give it a watch as it's great from start to end.
We won't ruin the result though we would suggest scoring the bout and leaving your scores in the comments section as we'd love to see people's views on the contest.
