Lewis Crocker says he "wasn't good enough" in his first fight against Paddy Donovan, but will be "the best version of myself" in Saturday's rematch at Windsor Park with the IBF world welterweight title at stake.
Crocker won the first fight between the pair at Belfast's SSE Arena in March by way of disqualification as Donovan, who was ahead on all three cards, was thrown out at the end of the ninth round for punching after the bell, having already been deducted points for fouls.
That was a final eliminator for the IBF title which was then in the possession of Jaron 'Boots' Ennis, but with the American opting to vacate and move up to light-middleweight, the all-Irish rematch was upgraded to world title status.
Opinions were split prior to the first meeting as to which of the pair would come out on top, but Donovan goes into Saturday's rematch as a firm favourite.
Crocker acknowledges his performance in March was well below what was required and is determined to produce much better this time.
"I'll leave my talking for the ring," Crocker said.
"I'm ready to put on the biggest performance of my life on Saturday.
"I wasn't good enough the last time so I need to be much better in all aspects. You are going to get the best version of myself. I've banked rounds with him, so I know what to expect. I'm ready."
