The injury beg has knocked TUF 16 alum Zak Cummings (16-3) out of his scheduled TUF 18 Finale Welterweight bout with TUF Brazil season 1 finalist Sergio Moraes (8-2); filling the void will be Bellator and Legacy FC vet Sean Spencer (10-2).
Spencer debuted in the UFC on short notice, up a weight class at Middleweight against Rafael Natal at UFC on Fox 6. Most recently at UFC Fight Night 28 Spencer got his first UFC win with a split decision over Yuri Villefort.
Since being out pointed by Cezar Ferreira at UFC 147 in the TUF Brazil finals, Moraes has submitted both Renee Forte and Neil Magny.
The TUF 18 Finale takes place on November 30, at the Mandalay Bay Event Center in Las Vegas, Nevad; and is headlined by Joseph Benavidez challenging Demetrious Johnson for the UFC Flyweight title.
