Gunnar Nelson and Dong Hyun Kim were the first fight announced for UFC Fight Night 99.
And now, the two welterweights will comprise the headline for the night, the promotion announced recently.
Set for November 19 from The SSE Arena in Belfast, Northern Ireland, the card will mark just the second stop for the Octagon in the country.
Nelson (15-2-1), who is from Poland but trains in Ireland with Conor McGregor, has gone 2-2 over his last four. He was bested by Rick Story in 2014 and Demian Maia last year around wins over Albert Tumenov and Brandon Thatch.
Both losses came via decision for Nelson, who started his MMA career 13-0-1. Each of his two most recent wins were via submission, as have been his last four victories overall.
Kim (21-3-1) has won two in a row and six of his last seven, losing only to current UFC champion Tyron Woodley since 2012.
