Apparently he damaged his hand in the fight with Ratchasak Kokietgym and is a serious doubt for the next Macau show http://www.asianboxing.info/asian-news/rex-tso-a-doubt-for-champions-of-gold
He's an exciting fighter, but his defense is really really leaky and his jaw isn't the best. Sad for him though. Very exciting.
There was a rumour that Kohei Kono wants to fight him in November...I might be cynical but...maybe...
