Here we go again!

MMAmania.com is proud to announce a UFC 137: "Penn vs. Diaz" contest give-a-way currently underway and in effect until Saturday night (Oct. 29, 2011) at 9 p.m. ET.

We will once again award several readers with high-end MMA apparel, courtesy of our friends at TrauMMA Combat. The grand prize winner gets a signed walkout tee from UFC heavyweight Matt Mitrione, worn during the actual pay-per-view event on Saturday night.

No worries, we'll also throw in a fresh one straight from the rack that you can wear to your local watering hole, as well as a TrauMMA Combat Stamp Hat. Second place will get their hands on a TrauMMA Combat Black V-Neck while third takes home a TrauMMA Combat Ops t-shirt.

So, what do you have to do to win? It's simple … follow us after the jump for complete details.

It's simple: Just provide your fight prediction for Mitrione's upcoming bout against Cheick Kongo on the main card of UFC 137 (ex. Mitrione defeats Kongo via technical knockout in Round 2 at 1:39; or Kongo defeats Mitrione via unanimous decision in round 3 at 5:00).

So it's winner, round, method and time. One entry per reader ... so make it count! If you pick a decision be sure to include the official time, as well as guess the potential scores for each round (10-9, 10-9, 8-10, etc.)

And to be on the safe side, all entries that pick a decision win must include a tie-breaker pick from the Mirko Filipovic vs. Roy Nelson fight. Same criteria as above.

To enter, leave your picks in the comments section below. Get moving! Contest ends Oct. 29 at 9 p.m. ET sharp!

Good luck!
