A lot of discussion has revolved around the NFL's policy regarding players who use marijuana. But now they might have to address what happens when a player's dad is caught with cannabis.

Dallas Cowboys quarterback Dak Prescott's dad was arrested on Saturday after police found marijuana inside the door of his Cadillac Escalade. Nathaniel, Dak's dad, was charged with a Class B misdemeanor and was let out of jail on a $500 bond.

Media reports say that Prescott's car contained less than two grams of marijuana. It's not entirely clear why he was pulled over by police in the first place, and what exactly prompted them to search his car which ultimately led to them finding the cannabis. 

Prescott is a somewhat controversial figure in the NFL. Last year he took part in the protests against police brutality by kneeling during the national anthem before games. And he's also the quarterback of the Dallas Cowboys, which obviously earns him a lot of hate from fans as well.

It would be interesting to see if Prescott uses his father's arrest to make a statement about marijuana legalization. Perhaps getting the quarterback of Cowboys behind legalization would help finally get it passed in football loving Texas.
