This is a solid fight between fringe contender Sultan and another fringe contender in Sharone Carter. Sultan has a win over John Riel Casimero but hasn’t fought since 2019. Sharone Carter has been active and in competitive fights where’s hes shown he can hang with fringe world level fighters.
I think Sharone Carter will out work Sultan over eight rounds and take a decision. Sultan will have ring rust and Carter is a decent fighter.
