Unbeaten American Terence Crawford has vacated his WBA welterweight world title, elevating compatriot Brian Norman Jr from interim to full world champion status.
Crawford, 36, won a world title in a fourth division when he beat Israil Madrimov to claim the WBA light-middleweight crown earlier this month.
The move signals Crawford's intention of staying at light-middleweight in pursuit of unification fights.
Norman Jr is undefeated in 26 pro bouts with 20 stoppages.
The 23-year-old captured the interim WBA title with a stoppage win over Giovani Santillan in May.
