Ronaldo Souza - StrikeforceThe UFC’s May 18 stop in Brazil for UFC on FX 8 may be headlined by a bout between Luke Rockhold-Vitor Belfort but it turns out the main event match-up won’t be the only clash on the card featuring a middleweight with ties to Strikeforce gold taking on one of the division’s top contenders. Though not confirmed, it appears former Strikeforce champion Ronaldo Souza will make his UFC debut at the show where he’ll collide with streaking powerhouse Costa Philippou.

MMAFighting was first to report the rumble. The bout will also give Souza an opportunity to fight in front of his countrymen for the first time in more than five years.

Philippou is 12-2 in his career and currently on a five-fight run including a finish of Tim Boetsch last December. Half of his wins have come as the result of a strike-based stoppage.

Though his hands have improved over the past few years, “Jacare” is primarily known for his exceptional ability on the mat. The 17-3 grappler has thirteen triumphs by way of submission including those over Alexander Shlemenko, Robbie Lawler, and Ed Herman.
