On 21 September 2001, fought against Raul Sosa at Tormenta en el Ring in Caracas, Venezuela. Maia defeated Sosa by TKO in just 48 seconds to win his MMA debut.

Maia next competed at Super Challenge 1, earning three victories in one night to be crowned the 2007 Super Challenge Champion in the under-83 kg division. In 2007, he competed in GFC – Evolution against Ryan Stout. Early in the first round, Stout's shoulder popped out of its socket after Maia reversing him into a mount, causing a stoppage due to injury.

It was reported on 7 August 2007, that Maia had signed a contract with the UFC. He was originally matched against veteran Marvin Eastman, but Eastman pulled out due to eye surgery. Ryan Jensen, who trained with Team Quest, was named as his replacement. The preliminary bout took place on 20 October at UFC 77 in Cincinnati, Ohio.

In the first two rounds, Silva appeared to mock his opponent, while also executing quick, precise striking.
