The game at Murrayfield will be the final opportunity for players to put their hands up for selection for next weekend's Aviva Premiership Rugby opener against Gloucester.
Dylan Hartley captains a squad which sees Ken Pisi make his first start of the summer and GJ Van Velze given the nod at Number 8.
Tomorrow's game is not being televised, but supporters can keep up-to-date with scores as they happen on the Saints' official Twitter feed. Highlights will be available early next week.
