The main event has an odd feeling to it, even though it should decide a lightweight title challenger.
If Benson Henderson beats Josh Thomson, he is in no man's land. He has already lost twice to UFC champ Anthony Pettis, including via first-round armbar in his last outing. That would suggest that Henderson is out of the title picture, no matter what, for a bit of time to come.
As for Thomson, he is in an inverse situation. A win over Henderson would likely clinch him a title spot, as he already had a scheduled title shot in December that fell through because of an injury to Pettis. So in theory a win for Thomson means a title fight, right?
Then you have to consider the pecking order at 155. TJ Grant was supposed to get a title shot, but he has been sidelined with concussion issues.
Gilbert Melendez could be another guy who challenges for the title, but he has apparently been avoiding a fight with Russian buzz saw Khabib Nurmagomedov, per MMAFighting.com, as has his training partner Nate Diaz (who is nowhere near the title picture despite saying that he is) according to MMA Junkie's John Morgan.
The main event has the potential to give Pettis his next title defense or just serve as a big-name main event. Either way, Thomson vs. Henderson is a fight you will have to watch to get answers.
