New Bellator 120 poster pic for 'Rampage vs. King Mo' pay-per-view (PPV) on May 17

It's being billed as "MMA's Biggest Grudge Match."

Bellator MMA has a new headlining attraction for its inaugural pay-per-view (PPV) offering, as the Bellator 120: "Rampage vs. King Mo" fight card has been turned inside out for the upcoming brouhaha inside Landers Center in Southaven, Mississippi, on May 17, 2014.

And it all started with a concussion to Eddie Alvarez, which bounced him from his lightweight championship trilogy against Michael Chandler (see his replacement here).

As the name suggests, Quinton Jackson will square off against Muhammed Lawal to complete the promotion's light heavyweight tournament in the new main event.

Jackson is 2-0 under the Bellator banner while Lawal is 4-2.

These two have a history dating back to their infamous van ride in 2009, which was moderated by then-Strikeforce prospect Bobby Lashley (watch it). They later squashed their beef, but renewed their rivalry after Jackson signed with Bellator MMA.

Then came their post-fight melee at Bellator 110 (video).
