Cam Newton. Manny Pacquiao. UFC 122.

We're in for a busy Saturday in sports.

Today, Manny Pacquiao will go head-to-head with Antonio Margarito in Arlington, Texas.

What's at stake?

Pacquiao is after his eighth world title in an eighth different weight division—a feat that has never been done in boxing. Margarito is looking to regain his reputation after being suspended from boxing for having a plaster-like substance concealed in his hand wraps following a match with Joshua Clottey.

On the Cam Newton front, the Heisman trophy frontfrunner is facing a lot of heat with allegations of a pay-for-play plan made to interested teams when he was being recruited late last year.

We've also got UFC 122 tonight.
