Vicente Luque will quickly shift his focus from a veteran of the Octagon to a fighter making his promotional debut Saturday at UFC Rochester.
UFC newcomer Derrick Krantz will replace Neil Magny in Saturday's co-main event against Luque, according to FloCombat's Nolan King.
Krantz's team confirmed the news in an Instagram post.
Magny was forced to withdraw from his welterweight matchup after failing a drug test Saturday, he announced on Instagram.
Krantz (24-10) is a former Legacy Fighting Alliance welterweight champion and makes his promotional debut with seven wins in his last eight fights, and is coming off a first-round TKO victory over Justin Patterson at LFA 63 in March. The 30-year-old has fought some tough competition, including current interim lightweight champion Dustin Poirier, Andrey Koreshkov, and UFC welterweight Alex Morono.
Luque (15-6-1) is riding a four-fight win streak which includes a TKO victory over Bryan Barberena at UFC on ESPN 1 in February. The Hardknocks 365 product has gone 8-2 during his UFC career, with all of those victories coming via stoppage.
UFC on ESPN+10 takes place this Saturday at Blue Cross Arena in Rochester, N.Y. The main event pits former lightweight champion Rafael Dos Anjos against Kevin Lee in a welterweight contest.
