ONE Championship middleweight titleholder Aung La N Sang took a major risk by fighting dangerous heavyweight striker Alain Ngalani in an open-weight bout today at ONE Championship 63. It was clear Ngalani’s (3-4) strength was an X-factor, but it couldn’t prevent hometown hero Sang (21-10) from locking in guillotine choke to win the main event at the 4:51 mark of Round 1.
