We're getting our first hint for the reason a sponsor has dumped a major team

This could very well be a case of musical sponsorships.

Earlier today, Subway announced it was terminating its sponsorship with Joe Gibbs Racing and driver Daniel Suarez. Now we're getting a hint as to why. It look like Subway may be shopping its sponsor money elsewhere, according to a tweet from the Sports Business Journal's Adam Stern.

This "this" that he refers to is the report that, according to ESPN,Subway has decided to move on.

Subway sponsored Suarez, who drives the No. 19 Toyota Camry. Subway, in a fairly cryptic statement,  said, "Due to circumstances beyond our control, Subway had to terminate its sponsorship of Daniel Suarez." A Joe Gibbs spokesman wouldn't talk about the exact reason Subway dropped its sponsorship, but said it has nothing to do with a violation of a morals clause.

In different times, losing Subway might not be that big of a deal. Subway only sponsored Suarez for four races.

But in these times this is a big deal. Teams are scrambling for sponsorship dollars, with drivers such as Kurt Busch, Matt Kenseth and Danica Patrick all scrambling for dollars.

Stay tuned.
