Abdul Razak Alhassan -- a budding MMA star who scored a crazy knockout at UFC 228 in Sept. 2018 -- was just found not guilty in his sexual assault case ... TMZ Sports has confirmed.
Alhassan was facing two charges after he was accused of raping two women inside a Saginaw, Texas home back in March 2018.
The two alleged victims claim they were partying at a bar in Forth Worth (where Alhassan worked as a bouncer) ... when the UFC fighter brought them back to one of their homes and sexually assaulted them.
