In 2007, Feijao took a major step towards prominence by competing in the team-oriented IFL: International Fight League (2006). That February he fought and defeated Devin Cole by an early round 2 TKO at the IFL event in Atlanta. Marcio Cruz defeated Feijao by disqualification while fighting on another IFL card, this time in Las Vegas. In the third round, Feijao delivered illegal kicks to Cruz which resulted in his first loss. After this bout, Feijao next moved down in weight to competed as a permanent light-heavyweight at Elite XC: Street Certified (2008).He fought John Doyle and won by technical knockout in over two minutes.From the International Fight League, Feijao moved on to EliteXC, where he fought Wayne Cole at Elite XC: The Return of the King (2008).

Eilers had lost the inaugural EliteXC heavyweight title fight to Antonio Silva, and decided to move down to the light-heavyweight division. EliteXC officials booked Feijao in a fight with Cyrille Diabate to crown the first ElitXC light-heavyweight champion. Diabete later withdrew from the scheduled November bout in Reno, Nevada. Feijao remained on the card, waiting to face an opponent who had yet to be named. The event did not transpire as a result of the promotion's closure in October 2008 because of financial pressures.
