The Phuket-based Syran fighter finished off Brazilian Jiu Jitsu black belt Christofer Silva (3-1) in the middle of the second round with elbow strikes while he was held on the ground.
This was Suleiman's second straight bout after overcoming tearing his ACL in October 2013 during a bout against Abdel Medjedoub.
Suleiman trains out of Phuket's Tiger Muay Thai & MMA Training Camp in Chalong.
