Rio de Janeiro -- The most-anticipated rematch in jiu-jitsu history ended with a bang today as Roger Gracie and Marcus 'Buchecha' Almeida met at the Gracie Pro event. 

The Olympic arena Carioca 1 hosted the jiu-jitsu spectacular, which featured a 15-minute superfight between the two jiu-jitsu legends. The match would serve to settle the score from their match in 2012, declared a draw under submission-only rules. 

Gracie used clever grip fighting to kill Buchecha's takedown attempts, stuffing a number of fast single-leg shots. 

Pulling to guard, Gracie reversed position and forced Buchecha to the turtle position. From there, he sunk in both hooks and patiently worked a collar choke that forced a tap at a little under seven minutes into the contest.
