Strikeforce’s upcoming September card that is expected to feature Ronaldo “Jacare” Souza’s title defense against Luke Rockhold along with a handful of other bouts appears to be getting two monumental additions to the card. MMA Junkie is hearing that the Sept. 10 card will also feature the semi-finals of the Strikeforce Heavyweight Grand Prix.

Multiple sources close to the promotion on Thursday told ( that an event set for Sept. 10 will host the third leg of the grand prix.

A host city has yet to be confirmed at the time of this writing.

Nothing is official yet, but if all the rumored match-ups go down as expected the card will look like this.

  • HWGP Semi-Final: Alistair Overeem vs. Antonio Silva
  • HWGP Semi-Final: Josh Barnett vs. Sergei Kharitonov
  • MW Championship: Ronaldo “Jacare” Souza vs. Luke Rockhold
  • King Mo Lawal vs. Roger Gracie
  • Gegard Mousasi vs. Mike Kyle
  • Josh Thomson vs. Maximo Blanco

That’s a heck of a card.
