While it doesn't increase the overall number of holdovers from TUF Brazil 2 (Leandro Silva having already been released) at least one more fighter will be getting a fight in the octagon coming off his time on the show.
Portal do Vale Tudo has the story, reporting that Luiz Dutra Jr., also known as "Besouro" (or Beetle), is indeed still under contract to the UFC. Although, no official announcement of his signing or potential date for his debut has been named.
Dutra was the no. 1 pick by Team Nogueira for the most recent TUF season, and defeated Werdum top pick Pedro Irie in the opening round. Unfortunately Dutra would later suffer a torn ligament in his right hand that prevented him from moving on in the tournament.
He's a long time vet of the sport, at 31, with a career that stretches all the way back to 2004. Despite that he's only 11-2-1 with both of his losses coming due to injury (the most recent from an ill advised jumping switch kick against Paulo Thiago in 2008). He has two wins over the UFC's Fabricio Camoes in his career and is currently riding a four fight win streak. With his aggressive power striking and willingness to take risks, he should make a fun addition to the welterweight ranks
Here's video of his Paulo Thiago fight for a nice encapsulation of his up and down sides:
