By now you've probably heard that what is expected to be called "UFC on FX 8" will feature Vitor Belfort vs. Luke Rockhold, the final Strikeforce 185-pound champion, on May 18. MMAFighting.com has also confirmed that former Strikeforce middleweight king Ronaldo "Jacare" Souza will meet Constantinos Philippou on the card, as well.
Souza (17-3, 1 NC) has won his last three fights in a row since losing the Strikeforce belt to Rockhold in Sept. 2011. The Brazilian jiu-jitsu specialist most recently defeated Ed Herman at the final Strikeforce event in January.
Philippou (12-2, 1 NC) will ride a five-fight winning streak into the fight. The former boxer is coming off a TKO win over Tim Boetsch at UFC 155 in December.
The UFC is expected to officially announce the card in the coming weeks.
