MMA Submission of the Day: Black-Belt Jon Olav Einemo Submits James Thompson

It has been over four years since heavyweight Jon Olav Einemo has fought in mixed-martial-arts, but he makes his return this weekend when he takes on a very dangerous prospect in Dave "Pee Wee" Herman.

In Einemo's most "recent" bout on November 12, 2006, he submitted James "The Colossus" Thompson in Rotterdam, Netherlands. Einemo's only defeat in MMA was against Fabricio Werdum at Pride 31.

At 6'6", the Norwegian fighter has a small height advantage over his opponent at UFC 131, but will the ring rust be a factor for him? The event will also feature a heavyweight main-event between powerhouse punchers Junior Dos Santos and Shane Carwin.

One advantage the 35-year-old has over many of his opponents is in his grappling ability. He became the ADCC Submission World Wrestling Champion in 2003 when he defeated Alexandre Ferreira.

The Brazilian Jiu Jitsu Black-Belt is also the only man to ever defeat Roger Gracie in the Abu Dhabi Combat Club Tournament.

It's going to be a long night if the Golden Glory team member can't get the fight to the ground.
