Another undercard scrap for EliteXC's Saturday Night Fights at the Prudential Center in Newark, N.J., on on May 31 was recently announced, according to FiveOuncesOfPain.com -- undefeated Brazilian jiu-jitsu black belt Wilson Reis (3-0) and Justin Robbins (8-3-1) will meet in a 140-pound showdown.

Reis just fought on the ShoXC Challenger Series card in Atlantic City, N.J., on January 25, beating Zach Makovsky with a second round choke. He is a decorated jiu jitsu specialist with a championship in 2004 at the prestigious Mundials tournament in the brown belt division.

In addition, Reis is well known in the competitive grappling world and has made a successful transition to mixed martial arts since his professional debut -- a unanimous decision win over Baba Shegeyasu last July at Extreme Challenge 81.

Robbins is more of a wrestler, but also likes to use submissions to finish his fights. In fact, he has three career victories by way of a submission.

This will be the first fight for Robbins under the EliteXC banner. His last showing was an impressive first round win at Warrior Concepts: "Valhalla Rising," during which he slapped an arm triangle on Jeff Hodges 47 seconds into the fight.

This one should come down to who executes their gameplan more effectively. Reis will obvioulsy be looking to showcase his jiu jitsu skills and Robbins will probably use his takedown defense to try and keep the fight standing.

EliteXC Saturday Night Fights undercard bouts will all be streamed live on ProElite.com for free prior to the 9 p.m. start time on CBS come May 31.
