They will travel to The Racecourse ground on August 05th.
"Obviously as a club we are very, very happy," explained Dragons managing director David Rhodes.
"I'm just glad that we can accommodate them and it's certainly one of the most prestigious draws we've had at the Racecourse Ground in recent history.
"It should remind the club and the fans of our former glory days when we were in Europe and will also give the lads a different type of opposition so close to the start of the season."
