The Tennessee Titans will unveil their new uniform and helmet design at a street festival Wednesday night, but the NFL is investigating a social media post from Monday claiming to show the new design.

The Tennessean reports that the league is investigating the post, which shows a No. 8 Marcus Mariota jersey with a slightly modified design.

Apparently the retail version of the @Titans navy jersey has leaked.

ESPN reports that if the league's investigation discovers the source of the leaked photo, which may have come from someone with ties to an apparel company, "there likely would be some form of punishment."

Of course, there's the possibility some prankster pulled a late April Fool's Day hoax with a little photo-editing software. Either way, Titans fans can see the real deal Wednesday on Lower Broadway in Nashville. The program begins at 6 p.m. local time, with the uniform unveiling at 7:30 p.m., followed with a concert by Florida Georgia Line
