Koike started the bout well, in fact it seemed that Kukiat's only notable connect in the opening round came when Koike was too comfortable. The Japanese fighter built on his success by scoring a knockdown in roudn 2, and then seemed to clearly win rounds 3,4 and 5 with the Thai typically looking for counters and fighting like a man with a sparring partner mentality. Although he had his moments it seemed that Kukiat was cruising to a decision loss.
In round 6 however Kukiat had a break through, leaving Koike with a seriously bad cut over his left eye. The cut bled significantly and forced the referee to take the local to the ringside doctor, who refused to allow the bout to go on. As a result Koike suffered his first stoppage loss and Kukiat claimed his first win, in what was a hugely surprising fashion.
