Tyrone McKenna believes he will unlock the "missing link" when he returns to the ring next month.
McKenna will move up to welterweight for his clash with Welshman Chris Jenkins on the undercard of Michael Conlan vs Miguel Marriaga at the SSE Arena on August 6.
The 32-year-old has promised another toe-to-toe show in front of the Belfast fans, and believes moving up to 147lbs will bring out the best in him.
