Bristol City's Frankie Artus will remain on loan at Cheltenham for the rest of the season.
The 20-year-old has enjoyed a successful month with the League One strugglers, scoring three goals in six starts.
Prior to his move to Whaddon Road, Artus had loan spells with Exeter, Brentford and Kettering but he has yet to make his first-team debut for Gary Johnson's side.
Meanwhile, striker Leon Constantine has returned to Northampton after a month's loan with the Robins.
Constantine scored once in six appearances in his time at Whaddon Road.
