Heading into UFC 103 against Frank Trigg on Sept. 19 from the American Airlines Center in Dallas, Texas, UFC welterweight contender Josh Koscheck will be making his fifteenth appearance inside the Octagon.

And on Saturday night versus "Twinkle Toes," he'll be doing it as a newly-minted jiu-jitsu brown belt.

"Kos" earned the honor last week after completing another chapter in his training under esteemed grappling mentor, Dave Camarillo.

In addition to being the head grappling coach at American Kickboxing Academy (AKA), Camirillo is the founder of Guerilla Jiu-Jitsu, a unique and innovative approach that combines Jiu-Jitsu with Judo.

Camarillo is a black belt under Ralph Gracie and used his experience in Judo to create the hybrid "Guerilla" system, which emphasizes the use of throws that segue directly into submissions on the ground.

That style can be complemented by a wrestler, like Koscheck, who knows how to shoot and score big slams.

The former Ultimate Fighter is an impressive 10-4 inside the Octagon since his debut back in October 2005. Despite a rare misstep against Paulo Thiago at UFC 95 earlier this year, the former division number one contender continues to improve and take himself to the next level.

Frank Trigg may have picked a bad time to make his Octagon return.
