Tom Ziller of NBA FanHouse has the details:
UPDATE, 3:30 PM: The Sixers have removed the image from the page. The page is now just a blank black page with the subject line “Sixers draft Evan Turner.” At the same time, the Sixers website now has blank black pages with the subjects and appropriate URLs for [DeMarcus] Cousins and [Derrick] Favors. This is straight-up CYA posturing — those pages were not live when the Turner one was first found. We tested them.
Indeed, the Sixers vastly underestimated the cunning of internet sleuths when they tried to apply that fix.
