Abel Trujillo is not happy with the way his lightweight clash with Gleison Tibau ended.

In the preliminary portion of UFC Fight Night 77 in Sao Paulo, Brazil, on Nov. 7, Trujillo vs. Tibau was over at 1:45 of the first round, when referee Keith Peterson stopped the contest believing that the Blackzilians fighter went out due to a rear-naked choke.

Trujillo immediately protested when the referee stopped the fight, and Tibau later admitted he didn’t feel his opponent tap.

Brazilian MMA Athletic Commission (CABMMA) chairman Rafael Favetti told MMAFighting.com on Sunday that the commission would only review the result if Trujillo appealed the decision, and that’s what his team did.

According to Blackzilians coach Jorge Santiago, Trujillo’s camp reached out to CABMMA and requested the paperwork so they can appeal the result, and they are confident that the decision will be reviewed.

After Trujillo files his appeal, CABMMA will contact Keith Peterson and ask if he’s 100 percent sure of his call. If the referee tells the commission he believes he’s made the right call, CABMMA won’t review the fight.

Trujillo (12-7, 1 NC) dropped to 3-3 with one no-contest following a loss to Tibau (33-11), while the Brazilian improved to 17-9 under the UFC banner.
