From a Washington Post story by Des Bieler headlined “Hello Darkness: Aaron Rogers to ponder his future in sensory deprivation”:

It remains to be seen if Aaron Rodgers becomes a member of the Las Vegas Raiders, but he is set to experience his own version of the Black Hole.

The Packers quarterback said he will immerse himself in a four-day “darkness retreat” to help him decide whether to retire, stay in Green Bay or push for a trade.
