First, a run-down of the particulars:
- Due to potential metric conversion issues and weight class changes, a limit of 148 pounds is observed for this list.
- Inception of the championship occurred on 11/27/1992, the first known professional fight taking place at or below 148 pounds. There was not an ideal, early entry point for this division’s lineal championship.
- Only a period in the mid 2000s saw fighters leave the division without losing. These situations were easily resolved in quick fashion by “best available” match-ups featuring 1/2, 2/3 or 1/3 ranked fighters.
Your current lineal Featherweight champion is Ilia Topuria
