Guernsey Raiders and Guernsey Ladies Rugby have named their squads for this Saturday's Siam Cup in Jersey, into which both go as holders.
Raiders got their hands back on the famous trophy for the first time since 2008 when they beat Jersey Reds 46-30 at Footes Lane last year.
Director of rugby Jordan Reynolds has named four debutants in his 22 - George Shannon, Elia Morisio, David Anderson and Harry Baron - who all came in for the club's maiden season in National Two South.
Guernsey Ladies, meanwhile, are going for an eighth straight Siam success this weekend.
Head coach Steve Evans, who is taking charge of his first senior Siam after Chris Griffiths stepped down in 2018, includes five new faces in his squad.
Prop Laura Sweeney and back Aimee Le Bachelet will both start at St Peter, with Asha Holberry, Megan Irven and Georgia Denziloe among the replacements.
All four matches this year will be played on the main pitch at Stade Santander International, with the Women's Siam at 12:15pm and the Siam Cup itself getting underway at 4:30pm.
