UFC 101: Declaration is taking place on Saturday, Aug. 8 at The Wachovia Center in Philadelphia, Penn. Since it is only a few days away, now is a great time to place your bets on who will come out on top.

Aaron Riley will be fighting Shane Nelson for the second time at UFC 101, but Riley won’t be calling it a rematch any time soon.

The experienced lightweight out of Seattle lost in 44 seconds at UFC 96 in March against Nelson when the referee intervened in a stoppage universally agreed upon to be premature.

Riley is listed as a -130 favorite to win, while Nelson is the underdog at +130.

Riley, who is 27-11-1, enters this weekend's fight eager to put the setback from earlier in the year behind him and that should make for an all-out war.

Nelson (13-3) will be looking to pull off the upset and prove last time was no fluke.
