Haywards Heath hope a touch of midfield experience can help them cause the shock of the National League season so far.
Heath, bottom of Division Three South after a tough opening to the campaign, play host to Barking, top of the table with three wins out of three.
The Essex club's successes include a win at Blackheath, who were 30-point victors at Whitemans Green last week.
Heath though have taken heart from their display in the last quarter of that game and hope the recall of centre Vince Rolandi can help steady things in midfield.
Skipper Alex Meredith, who takes over goalkicking duties tomorrow, said: "Vince came on last week and made an impact.
"He has been playing well in the twos and gets the nod over Nick Stocker, which is a bit tough on Nick."
James Arthur starts in the back row in place of Dave Wattam Barking's Matt Bowden starts a four-week ban after being found guilty of stamping in the recent Powergen Cup defeat by Bedford.
Barking stayed up last year after losing their first six games and Meredith added: "That shows what can be done. It's still early days."
Sussex's two remaining Powergen Intermediate Cup survivors meet each other.
It could be a decent contest too as Worthing visit a Lewes side flying high in London Three South East.
Grant Gatford is back in the Lewes side but Jon Quirk, so impressive last week, is unavailable so Terry Butler starts.
Worthing coach Ian Davies said: "We are keen to keep the momentum going."
The day's Junior Cup action gets underway early as Old Brightonians host Isle of Wight at Waterhall with an 11am start.
OBs have made a good start to the season and spokesman Peter Rumney said: "This is our biggest cup game for some time."
The Sussex RFU are continuing to ask all other clubs involved in cup ties to confirm kick-off times. It is feared some teams and referees might turn up at the wrong time amid talk of clubs delaying their games to allow players to watch the England v South Africa match.
