Rafael dos Anjos will face Kevin Lee in a battle of top welterweights at UFC Fight Night: Rochester on May 18, sources confirmed to ESPN.
The Democrat and Chronicle in Rochester, New York, first reported the matchup.
Dos Anjos is a former UFC lightweight champion who claimed the belt in 2015 in a victory against Anthony Pettis. He followed that with a win against Donald "Cowboy" Cerrone but is 4-3 in his past seven fights.
Dos Anjos, who moved up to welterweight in 2017, will look to rebound from two consecutive losses, unanimous-decision defeats to Colby Covington and Kamaru Usman, respectively.
This will mark Lee's first fight at welterweight after spending his career in the lightweight division. He has won six of his past eight but is coming off a unanimous-decision loss to Al Iaquinta in December.
A bout between Sijara Eubanks and Aspen Ladd, two top UFC female flyweights, will also be on the card.
