The match against Bognor represents the turning of the season for Field as they meet for their return fixture.
When the teams last met Bognor took the honours with a 33-5 win. Since then the royal town has slipped from leading the league to sharing a sturdy second place with fellow highfliers Millbrook.
Bognor have lost only two games so far this season, a close first-week defeat against mid-table Fareham and a comprehensive loss to league leaders US at the start of December.
