As part of the move, the 20-year-old has also agreed terms with the Club, extending his stay at the Sussex Transport Community Stadium.
Ollie is no stranger to the Rooks, having spent the final portion of last season on loan at the Isthmian League Premier Division side.
The winger featured against the Rebels during pre-season, as he came on as a substitute in the 2-2 draw at the Dripping Pan last month.
Best of luck for the season, Ollie!
