Former UFC middleweight No. 1 contender Paulo Costa recently did a live session on his YouTube channel in which he revealed a desire to face Robert Whittaker for the interim 185-pound belt.
“Whitaker is No. 1 in the rankings, I’m No. 2,” Costa said. “Once [Israel] Adesanya goes up to light heavyweight, it makes sense to have an interim title fight. I’ve already talked to [UFC president Dana White] and he said he would love to see that fight.”
There is recent precedent for such a move in the middleweight division: When Whittaker, who was the reigning champion at the time, was unable to compete at UFC 236 because he was recovering from hernia surgery, the promotion booked an interim title clash between Adesanya and Kelvin Gastelum.
