Mixed martial arts career
Guida appeared on The Ultimate Fighter: Team Nogueira vs. Team Mir and was eliminated in the first episode for failing to make the 206 lb weight limit by 1 pound.

Following this, as a last minute replacement for Ken Shamrock, Guida faced former WWE pro wrestler Bobby Lashley. Guida lost by unanimous decision. Before his bout with Lashley, he and Guida got in a scuffle at a pre fight press converence.

Guida then suffered losses to UFC veteran Jeremy Horn and top Polish contender Mamed Khalidov, but overcame his losing streak with a KO win over former UFC fighter Logan Clark, ending the fight with a barrage of punches in the first round in Clark's hometown of Rochester, Minnesota.

In 2009 Jason was set to take on 2011 ADCC World Championship Nottingham Gold Medalist and current UFC fighter, Vinny Magalhães in the main event of "Carolina Crown 2" as a late replacement for Lance Evans, the brother of UFC star Rashad Evans. He later dropped out of the fight due to a lower back injury sustained during training, he was replaced by Bellator fighter Chris Davis.

In 2010, Guida then tried out for The Ultimate Fighter 12 in the light heavyweight division but was unsuccessful when the light heavyweights were cut in favor of a lightweight only season.

Guida stepped in as a replacement and fought Justin Lemke at Bellator 29 in a 210 lb catchweight bout. Guida weighed in 5 lbs over the catchweight limit and the fight was changed to a 215 lb catchweight bout.

Guida was involved in a backstage scuffle with heavyweight Sean McCorkle at UFC 124 in which members of Guida's camp and Guida himself warned McCorkle that he was a Made man.

In 2011, Jason joined his brother Clay and started training under top mixed martial arts trainer, Greg Jackson, in a attempt to reinvent his fighting career.
