portion of the ad in question. Brandon Flowers (upper left), Eric Berry (upper right)

So what are the Kansas City Chiefs doing on their extended time off during the lockout? Two are advertised to be involved in a porn star party in Miami.

An ad for the Exxxotica Expo 2011 shows Chiefs defensive backs Brandon Flowers and Eric Berry in their uniforms and lists them as hosts for the event. An NFL legal team is looking into the matter and is concerned about protecting the league’s intellectual property rights. No comment from the Chiefs or the players yet.
