Did Ohio State QB Braxton Miller Commit NCAA Violation with Instagram Post?

Ohio State coach Urban Meyer currently has quite the 2015 quarterback battle going, with three dynamic athletes to choose from. However, has the competition already narrowed to two players?

On Tuesday night, Buckeyes senior quarterback Braxton Miller raised some eyebrows with an Instagram post that showed him "endorsing" AdvoCare (nutrition) products:

That post certainly seems like it could create a bit of a problem.

According to the NCAA, a player is not eligible if he or she gets paid to promote a product or service: "You are not eligible in any sport if, after you become a student-athlete, you accept any pay for promoting a commercial product or service or allow your name or picture to be used for promoting a commercial product or service."

Many commenters voiced their concern to Miller about a possible violation. The quarterback eventually deleted the post.

It remains to be seen whether this is in fact an NCAA violation. It's possible that Miller is making some money by working part-time for the company. After all, Miller is listed as an AdvoCare distributor on the company website (h/t College Spun).

Update from Tuesday, March 31

According to Ari Wasserman of the Northeast Ohio Media Group, Ohio State expects "a secondary violation with no eligibility lost and a letter of education for Miller to be the punishment."

Buckeyes coach Urban Meyer talked about the situation on Tuesday, via Wasserman:

"

I shouldn't comment on things I don't know about. I don't know, other than they are telling me they think it's good. I think it's going to be OK. People are asking me - "It's all good, it's done?" I don't know. 

It's been told to me that everything looks to be OK. They are just doing their due diligence and making sure.

"

Bleacher Report's Ben Axelrod did some research and was able to find something interesting on the matter: 

Ohio State is looking into the situation, per James Grega Jr. of The Lantern (Ohio State's student newspaper):

Although it seems hard to believe that a fifth-year senior would risk his remaining eligibility with a post like this, it is possible that Miller made an honest mistake. Only the NCAA can determine whether it truly is a violation. And you can bet it will look into the matter.
