Wagnney has trained in Brazil with teammates under Antônio Rodrigo Nogueira and has been linked to Renzo Gracie's Academy.

After losing for the first time in his career via controversial split decision to Jeff Curran, Fabiano ventured into the International Fight League.

He then fought LC Davis and became IFL Featherweight Champion with a submission victory by armbar near the close of the first round.

This was after dropping down to 145-pounds after defeating John Gunderson at 155-pounds in his previous IFL World Grand Prix fight.

In what was dubbed as an archetypal fight between wrestler and Brazilian jiu-jitsu expert, Fabiano won by knocking out Lierly at 0:37 of the first round.

Near the end of the round he threw a left jab which Lierly parried partially, but connected a flush right hook to knock out the challenger convincingly and conclude his first title defence.

[2] Fabiano was defeated by Semerzier by submission via triangle choke in the first round, ending his eight-fight win streak.

Wagnney Fabiano is married to Rachel Alves Romero dos Santos since 1998 and the couple has two daughters and a son.
