5. Tureano Johnson
The 31-year-old is Golovkin’s IBF mandatory, having outpointed Eamonn O’Kane in October. Although he was stopped by Curtis Stevens – a former Golovkin victim – last year, Johnson is a decent middleweight with a strong punch.
While Golovkin would enter as a heavy favourite, fighting Johnson would allow him to fulfill a mandated obligation while keeping busy before facing Canelo.
