» Fighter: Matt Arroyo

Heavyweight “Hungarian Nightmare” Christian Wellisch (8-4) will fight “Irish” Jake O’Brien (10-2) and lightweight “No Regard” Matt Arroyo (3-2) will face Daniel Cramer (2-0) at UFC 94 in Las Vegas 31 January, the organization announced Monday.

Wellisch was KO’d by Shane Carwin (9-0) at 0:44 of round one at UFC 84 in May.

O’Brien is coming off two consecutive losses, first to Fighters.com’s third-ranked heavyweight “Pitbull” Andrei Arlovski (14-5) via second-round TKO in March, then to Cain Velasquez (4-0) via first-round TKO in July.

Arroyo lost his last fight to “Immortal” Matt Brown (9-7) via second-round TKO in the TUF 7 Finale in June.

Cramer’s last fight was a submission loss to Timothy Credeur (10-2) during The Ultimate Fighter 7.

Three TUF champions highlighted the action in Las Vegas Saturday night: the original, the past, and the future.

The future shines brilliantly for The Ultimate Fighter’s newest blast into the mainstream consciousness, Amir Sadollah (1-0).

In his professional debut, Sadollah tapped “Doberman” CB Dollaway (6-1) in an armbar at 3:02 of round one to win the seventh season of the popular SpikeTV reality show contest.

“Nightmare” Diego Sanchez (19-2), one of the two original Ultimate Fighters, looked physically fitter than ever in his third-round TKO of American Top Team’s Luigi Fioravanti (12-4) at 4:07.

After back-to-back “embarrasing” losses, “Spyder” Kendall Grove (9-5), TUF 3 champion, recaptured past glory in a three-round split decision over former UFC titlist Evan Tanner (32-8).

The likeable young TUF walk-on from Virginia, Sadollah, versus the cocky All-American favorite, Dollaway, was a rematch of an exhibition fight fought on the final episode of last season’s The Ultimate Fighter.

Saturday’s finish was almost a replay of that fight’s end.
