Worthing coach Ian Davies has identified the trip to Portsmouth as a key date in their bid for promotion from London Two South.
Paul Todd returns in place of winger Mike Kimmer and there is a start for flanker Jodie Levett.
East Grinstead's survival battle in Three South East sees them host a Charlton Park side still eyeing promotion while Bognor are unchanged as they entertain Folkestone towards the top of Four South East.
Both Grinstead and Bognor are also in action on Sunday when the Sussex Trophy gets underway. Gs' visitors are Hove, who have made nine changes, including seven in the pack, from the side which lost at Beccehamians last Saturday.
No. 8 Carl Pittaway is the only forward to keep his place. Last season's runners-up Chichester are at Heathfield while Crawley will look forward to their home clash with higher division Brighton.
Winners of tomorrow's two delayed Sussex Intermediate Shield ties will qualify for the Trophy.
