Henry linked up with the Eagles in the summer of 2017 after impressing on trial during the previous season, where he played once for Palace's under-23 side.
The teenager made his professional debut at Peterborough United back in October 2015 when he came on as a substitute for Posh in a 5-3 victory over Millwall, and later that season he also turned out on loan for Soham Town Rangers in the Isthmian League.
Last season saw him make 12 appearances for National League North side Boston United during the first half of the campaign, before he was allowed to train with the Eagles.
He is currently on loan with Maidstone United.
