The 18 year olds will both be available for selection for the Scorpions’ first league match of the season on Good Friday away at Gloucestershire All Golds.
Despite missing Scorpions’ two Cup matches in March, playing six games at a high level has given them some much needed experience ahead of the league season.
Full-back Jones said: “The opportunity to play in France was one in a million. Even though we didn’t get the results we wanted, it was such a good experience and hopefully Zak and I can bring it back and take it into the Scorpions’ training and games.
“We played some games played out of position which helped us understand the plays in different areas on the field.”
Hooker Williams added: “I loved every minute of it. Playing in France was a great experience and I can’t wait to jump in to a Scorpions jersey and play for them this year in League 1. I know that’s going to a be a big challenge but I can’t wait to get going.”
