A middleweight matchup between season four veteran of The Ultimate Fighter Jorge Rivera and one-time World Extreme Cagefighting competitor Nissen Osterneck has been finalized for UFC Fight Night 18 on April 1.

MMAjunkie.com was the first to break the news of the matchup.

Rivera is a eight-year veteran of the sport who last competed at UFC 85 this past June, where he lost to Danish kickboxing specialist Martin Kampmann via submission in the first round. Prior to the loss, Rivera recorded a first round knockout upset against TUF 3 middleweight champion Kendall Grove at UFC 80.

He will look to get back on track against Osterneck, who is coming off the first loss of his career this past November against former NCAA champion Jake Rosholt. Competing against Rosholt during a televised match at WEC 36, Osterneck was TKO’d by punches at 3:48 of round 2. The Hawaiian native has also competed for Mark Cuban’s HDNet Fights promotion in the past.

UFC Fight Night 18 will take place at the Sommet Center in Nashville, Tennessee. The two-hour Spike TV broadcast will be headlined by former WEC welterweight champion Carlos Condit making his UFC debut against Martin Kampmann and will serve as a prelude to the season premiere for the ninth season of The Ultimate Fighter.

Additional reported matchups for the UFN 18 include TUF 8 lightweight champion Efrain Escudero vs. Jeremy Stephens, TUF 8 light heavyweight champion Ryan Bader vs. Carmelo Marrero, Junie Browning vs. Cole Miller, Tyson Griffin vs. Rafael dos Anjos, Matt Horwich vs. Ricardo Almeida, former WEC welterweight title challenger Brock Larson vs. newcomer Jesse Sanders, Aaron Simpson vs. Tim McKenzie, Steve Steinbeiss vs. Ryan Jensen, and Rob Kimmons vs. Joe Vedepo.
