From what we understand Tso's original opponent, Japan's Atsushi Kakutani (14-4-1, 7), has been forced out of the bout with a training injury. Kakutani, who lost in a WBC Light Flyweight world title bout last year, has been replaced by Thailand's Tiger Tor Buamas (17-1, 12) who will be hunting his 3rd victory following his shock upset loss to Alie Laurel back in January.
Some in the Hong Kong press have indicated that this is a "much tougher" fight for Tso though we'd not be that sure in all honesty. Tiger's record is certainly better on paper but a loss, just 3 fights ago, to Laurel is a worse result than losses to either Teiru Kinoshita or Adrian Hernandez, such as the two most recent losses for Kakutani.
As for Tso we don't really think their will be much of a change tactically. We don't mean to be harsh but we think Tso knows what works for him and that's aggression, pressure and action, things he'd use against either Kakutani or Tiger.
With Tso's last bout, a war with Mako Matsuyama, being a show stealer we assume that there will be a lot of attention on Tso's contest here. If he's in another action packed brawl we may well see him go from local attraction to an international star.
