The UFC has lined up a card to go opposite Bellator that will feature several top names, as Gegard Mousasi and Ronaldo “Jacare” Souza now headline UFC Fight Night 50.

Set for September 5 from the Foxwoods Resort Casino in Ledyard, Connecticut, the event will go head-to-head with Bellator 123.

Along with a five-round main event between middleweight contenders Mousasi and Souza, the card also recently gained heavyweight action pitting Alistair Overeem against Ben Rothwell and Matt Mitrione vs. Derrick Lewis, along with Nik Lentz-Charles Oliveira.

Mousasi (35-4-2) stopped Mark Munoz earlier this year, earning a first round submission victory. Prior to that, he dropped a decision to recent title-challenger Lyoto Machida. Souza (20-3) is on a six-fight win streak and will be looking to avenge a 2008 knockout loss to Mousasi.

Overeem (37-13) is coming off a decision win over Frank Mir, while Rothwell (33-9) hasn’t competed since last year due to a suspension for having elevated levels of testosterone.

Mitrione (7-3) was scheduled to meet Stefan Struve earlier this month, but the bout was scrapped when Struve passed out backstage. Lewis (11-2) moved his win streak to five in a row with another first round finish of Guto Inocente in his most recent fight.

Lentz (25-6-2) and Oliveira (18-4) fought back in 2011, with the contest being stopped in the second round after an illegal knee. Lentz has won four of five, while Oliveira is on a two-fight win streak.
