Jersey have continued rebuilding for next season with the signings of Alex Rae and Niall O'Connor.
Former England Sevens international Rae makes the switch from Wasps, with the 27-year-old lock having previously played for Bedford.
O'Connor, 25, joins the Islanders from Ulster to add to the competition for the fly-half shirt.
Rae and O'Connor follow Grant Pointer, Ben Maidment and Aaron Penberthy in signing for the RFU Championship club.
However fly-half Michael Le Bourgeois is poised to leave the club after rejecting a new contract.
Jersey director of rugby Ben Harvey said: "Mikey had an offer some time ago to stay with us for next season, but he has elected not to sign the new deal that was offered, and we now understand that he and his agent are looking at alternative offers with other clubs."
