Another former Strikeforce champion will enter the Octagon for the first time at UFC on FX 8, as Ronaldo “Jacare” Souza is expected to meet Costa Philippou. The bout was first reported by MMAFighting.com.

The card takes place May 18 from Brazil, with Vitor Belfort meeting Luke Rockhold in the main event.

Souza (17-3) is set to fight for the first time in the UFC, and is currently on a three-fight win streak. He topped UFC veteran Ed Herman in Strikeforce last month.

Philippou (12-2) is 5-1 with the promotion, including a TKO victory over contender Tim Boetsch in late 2012.
