Sean Santella’s long-awaited UFC debut, which was scheduled to come on short notice, will apparently have to wait.

Earlier this week, UFC officials announced Santella (15-5-1 MMA, 0-0 UFC) had stepped in for injured flyweight champion Demetrious Johnson (24-2-1 MMA, 12-1-1 UFC) and would fight Wilson Reis (20-6 MMA, 4-2 UFC) later this month at UFC 201.

However, Santella today announced those plans have been scrapped because “they said I need more medicals done … (and) there’s just not enough time before UFC 201” (via Twitter):

I'm sad to announce my UFC debut has been cancelled. I hope @seanshelby sees that ill fight anyone at anytime. @ufc pic.twitter.com/2Ob1GVnXS9 — Shorty Rock (@Srock125) July 16, 2016

UFC officials haven’t made a formal announcement, and it’s not clear if Reis will remain on the card.

UFC 201 takes place July 30 at Philips Arena in Atlanta. The main card, including a welterweight title fight between champ Robbie Lawler and Tyron Woodley, airs on pay-per-view following prelims on FS1 and UFC Fight Pass, though the bout order hasn’t been finalized.

Santella, a New Jersey-based fighter, owns 10 submissions in 15 career wins. The 31-year-old CFFC and ROC vet is riding a two-fight winning streak with seven wins (and one no-contest) in his past 10 bouts.

With the change, the latest UFC 201 card now includes:

Champ Robbie Lawler vs. Tyron Woodley – for welterweight title

Karolina Kowalkiewicz vs. Rose Namajunas

Matt Brown vs. Jake Ellenberger

Erik Perez vs. Francisco Rivera

Ed Herman vs. Nikita Krylov

Jorge Masvidal vs. Ross Pearson

Wilson Reis vs. opponent TBA

Damian Grabowski vs. Anthony Hamilton

Michael Graves vs. Bojan Velickovic

Cesar Arzamendia vs. Damien Brown

Ian McCall vs. Justin Scoggins
