"Sorry about my guy in the back getting dressed in that photo."
Chicago Bears star Brandon Marshall tweeted a photo of himself in the locker room this week ... unaware, apparently, that a teammate was naked behind him.
Marshall had just received a package from the University of Central Florida, his alma mater, and proudly posted a photo of himself in shirt the school sent.

The inadvertent full-moon photobomb received wide distribution on the Internet, and Marshall quickly realized his mistake, deleting the photo and tweeting:
Apology amusingly accepted, Brandon.
