NCAA Investigating Manziel

Leave it to Johnny Manziel to turn an ordinary Sunday into chaos.

This time, it wasn't a Twitter rant or being spotted at a frat party on the University of Texas campus. No, this time it's serious business.

According to ESPN, Manziel is being investigated for receiving money for signing autographs down in Miami during the BCS Championship Game. Manziel and autographs have been an issue before, but this is the first time he's been accused of directly receiving cash for them.

A couple of sources told ESPN's Outside the Lines that Johnny Football agreed to sign memorabilia for autograph broker Drew Tieman in exchange for a five-figure flat fee during his trip to Miami for the championship game. The sources said they witnessed the signing, though neither saw the actual exchange of money.

If true, Manziel would be ineligible for the 2013 season. Proving whether or not Manziel took the money is going to be difficult unless they find some kind of confirmation that this transaction actually took place.

Since he is a current athlete, Manziel is required to turn over any information pertaining to this investigation if asked by the NCAA.

Manziel has not commented yet, but Texas A&M has said that Manziel denies the charges. The NCAA hasn't exactly hit a home run lately with its investigations, so unless there is hard evidence, this will go the way of the dodo bird, as well.

The question now is, if the NCAA isn't finished investigating before the season starts, what does Texas A&M do? Do they risk playing Manziel or do they wait and see what happens?

This has to be Kevin Sumlin's worst nightmare come true, and he may not be waking up from it any time soon.
