SSE Arena, Belfast, Ireland - IBF super flyweight champion Jerwin Ancajas (28-1-1, 19 KOs) easily retained his title with a sixth round stoppage of previously undefeated Jamie Conlan (19-1, 11 KOs), who went down four times in the contest.

An odd occurrence in the very first round, where Conlan went down on a very delayed reaction where no punch was thrown. It seemed that he may have suffered some type of leg or knee injury, but it was never cleared up and he got back to his feet to continue fighting with no obvious sign of injury.

In the second round, things didn't get any better for Conlan, as he suffered a bad cut around his left eye from a clash of heads. Conlan was having his moments, but it was Ancajas with the better pressure and workrate.

In the third, Ancajas was really working over Conlan with hard shot to the head and body. Conlan nearly went down from a hard hook to the body, but a moment later he did go down from some follow-up shots and seemed to be in serious pain. He was able to make it to his feet. He was battered some more to the body and managed to make it out of the round.

Ancajas came out picking is punches in the fourth round. He was stalking Conlan by pushing him back and putting his punches together. Conlan was fighting back and once again he was hurt really bad to the body against the ropes, as Ancajas was lighting him up with combinations. Near the end of the round, Conlan went down for a third time from shots to the body.

In the fifth, Conlan was holding his ground as the Ancajas continued to pepper him with hard shots - especially to the body. There was a brief break as Ancajas was warned for straying low with some of his shots. A moment later Ancajas lost a point for what seemed to be another low blow that sent Conlan down to his knees. Near the end of the round, Conlan almost went down from another hard shot.

Conlan was pressing forward in the sixth, hoping to make things happen. He was dropped for a fourth time from a right hand to the side of the head. And this time the contest was waved off.

Jamie is the brother of hot prospect and Irish Olympian Michael Conlan.
