The Namibian-born forward was called up to Eddie Jones' England squad for an uncapped test match against the Barbarians, coming off the bench in the 21-52 loss.
He was also named in the squad for England's 2022 rugby union tour of Australia but did not feature in any matches.
It was later revealed that Schickerling was ineligible for England, as the residency qualification period was extended from three to five years during his stay in the country.
Schickerling has also had stints with Chinnor in National League One and Cornish Pirates in the RFU Championship.
