The 20-year-old has played with both Cambridge United and Northampton Town but has failed to make an impact this side of the Channel.
The giant marksman left The U's last November after scoring just four goals in 18 games for the club, and a loan spell with The Cobblers failed to ignite his spell in England.
The former Nantes man has been training with French Second Division side Besancon during the summer but they could not afford to sign the former French Under-19 international.
One now says that he is hoping to prove himself by earning a permanent contract with The Red Dragons.
"I hope this is the chance I need to get back into the Football League and I will do my best over the coming days and weeks," One told the club website.
One could make his first start for Denis Smith's side in their reserve fixture with Rochdale at The Racecourse Ground on Tuesday.
