The bout is expected to go ahead as scheduled, with Tafa forfeiting a percentage of his paycheck to Hunsucker for coming in heavy.
It adds to what has already been a wild year for the Auckland-born fighter, involving a controversial loss, a compound fracture in his hand and a new four-fight contract with the promotion.
An interesting stylistic matchup, Hunsucker has looked at his best when he mixes his strong grappling game in, with four of his seven wins coming by submission. He has, however, shown an affinity for the stand-up game, happily exchanging strikes in the pocket with his opponent - an area where Tafa is most comfortable.
"I've seen that he's got a bit of grappling in him, but he's not too hesitant to throw," Tafa said. "If he brings that same energy, so be it – I'll finish him. If not, we'll see where he takes it."
The Australia-based 28-year-old was one of three fighters on the card to miss weight, with Macy Chiasson and Sijara Eubanks missing the mark for the women's featherweight (65.7kg) and flyweight (56.6kg) divisions respectively.
Chiasson's weight (67.3kg) was the highest registered by a women's UFC fighter in the promotion's history, with featherweight being their highest women's weight class.
