The UFC Fight Night 256 lineup on May 17 continues to fill out with the addition of two notable matchups.
Melquizael Costa will take on Julian Erosa in a featherweight matchup, while Sodiq Yusuff and "The Ultimate Fighter 32" winner Mairon Santos clash in a lightweight contest at the UFC Apex in Las Vegas (ESPN+).
Two people with knowledge of the bookings told MMA Junkie of the matchups on Wednesday following initial reports from MMA Fighting and AG Fight. The people requested anonymity because UFC hasn't officially announced either matchup.
