A neck injury has forced Alessio Di Chirico (10-2 MMA, 1-2 UFC) to withdraw from UFC on FOX 25.

Stepping in for the Italian fighter is LFA middleweight champ and octagon newcomer Eryk Anders (7-0 MMA, 0-0 UFC), who will make his short-notice UFC debut against Rafael Natal (21-8-1 MMA, 9-6-1 UFC), multiple people with knowledge of the situation told MMAjunkie. They requested anonymity because the information hadn’t yet been made public.

UFC on FOX 25 takes place July 22 at Nassau Coliseum in Long Island, N.Y. The event’s main card airs live on FOX following prelims on FS1 and UFC Fight Pass.

Anders brings an undefeated professional record to the octagon, training out of Spartan Fitness. A former linebacker at the University of Alabama, he outpointed Brendan Allen this past month to capture the LFA middleweight crown.

Natal is in need of redemption after losing back-to-back bouts. The Brazilian fell short on points against recently minted UFC interim middleweight champ Robert Whittaker, and was then knocked out this past November by Tim Boetsch at UFC 205.

A timetable for Di Chirico’s return is to be determined. He most recently was submitted by Eric Spicely in January at UFC on FOX 23.

With the change, the finalized UFC on FOX 25 card includes:

MAIN CARD (FOX, 8 p.m. ET)

Chris Weidman vs. Kelvin Gastelum

Dennis Bermudez vs. Darren Elkins

Patrick Cummins vs. Gian Villante

Thomas Almeida vs. Jimmie Rivera
