Though he was not the only player to do so, former Florida Gator Tim Tebow made famous the practice of using his eyeblacks for communicating a message.  The NCAA football rules committee has now decided to ban the practice, leading some to dub it the “Tebow Rule.”

Under some interpretations, the practice of putting such text anywhere on the sports uniform was already prohibited, and the rules committee “clarified” that prohibition to include the players’ eyeblacks.
