The 21-year-old Palace Academy graduate heads out on loan for the first time to link up with the Scottish Championship side.
An attacking midfielder, Raymond has been with Palace since Under-9s level, and was twice named in senior matchday squads last season. He registered three goals and four assists in 22 appearances for our Under-21s last season.
Raymond has previously represented both England and Wales in youth international football, twice playing for the latter at Under-21s level.
Everyone at Palace would like to wish Jadan the best of luck for his loan move.
