Four Under-18s are on national duty, while the Under-17s team will be looking to take the form from their recent win over Saracens into Sunday's clash with England Under-16, being played at King Edward's School in Oxford.
There will be plenty of insight into how the opposition will play, however, as the Saints team will be coming up against five of their own - Paddy McDuell, Rotimi Segun, Freddie Davison, Henry Peck and Garth Spencer - who are with England Under-16 for a two-day training camp this weekend.
The game against the Saints Under-17s is part of the build-up towards England Under-16s' April internationals against Italy and Wales.
If you're in the Oxford area feel free to pop along and watch. Otherwise head to the Saints' Twitter feed for regular score updates!
