Richard Langley, who played for Hereford United last Tuesday against Southampton, has moved to Cheltenham.
He is set to play for them in their friendly at Oxford tomorrow.
The Robins have used 34 players so far this season in friendlies.
One player not lining up for the Robins is Port Vale striker Marc Richards. He has rejected a £100,000 move to Whaddon Road after accepting a new deal with the Valiants despite two seperate contract offers from Keith Downing.
