It's Christmas, and in addition to all of the festivities, we as MMA fans will also be treated to arguably the biggest rematch our sport has ever seen when Chris Weidman and Anderson Silva meet up for the second time at this Satruday's UFC 168. 

The tension is rising to an all-time high, but it's still unpredictable as to who is going to win this monumental bout.

The UFC released their traditional 'Countdown' series to promote the fight, and not surprisingly, it's a good one. Check it out while you open your presents and have a very Merry Christmas!
