Pryor, a left-footed player, has been plying his trade at the Eredivisie club since 2006 but his immediate future remains unclear.
The 24-year-old's talent is believed to have caught the eye of Robins manager Gary Johnson, who is keen to take a closer look at his qualities.
Van der Kraan told the club's official website: "For Anduele there is an invitation for a trial at Bristol City.
"At the moment I don't know if he will use that option. The only thing I know is he is thinking about it."
