Watch Strikeforce: Overeem vs. Werdum Live On Showtime

Mixed Martial Arts returns to Showtime with the Strikeforce World Grand Prix Heavyweight Tournament on Saturday, June 18, 2011, 10:00 PM ET/PT at the American Airlines in Dallas, Texas.

Two quarterfinal matchups will take place on June 18. In the main event current Strikeforce heavyweight champion Alistair Overeem takes on the Brazilian Jiu-Jitsu fighter Fabricio Werdum the first man to submit the legendary Fedor Emelianenko. Werdum also holds a 2006 submission victory over Alistair Overeem and Alistair is looking to get some payback.

The second quarterfinal pits heavy handed slugger Brett “The Grim” Rodgers against former UFC champion and PRIDE fighting veteran Josh Barnett.

The popular female MMA fighter Gina Carano was scheduled to make her return to the cage on the undercard but was pulled from the card by her doctor even though Gina Carano was cleared to fight by the Texas regulatory body.
