Former Reading lock John Salisbury has been handed a Haywards Heath debut in the battle for National League survival.
Salisbury has been with the club for three seasons and is given the nod after a series of fine second team displays.
He joins Rick Ure in the second row as Heath face a long awayday in Division Three South.
This time the opponents are Norfolk-based North Walsham, currently third in the table.
Heath skipper Alex Meredith said: "We've played first, second, third and fifth in the table in six weeks and this is another tough one for us.
"It has been quite hard for us so far but we will go there with confidence.
"We are certainly not going there thinking we will lose the game.
"What we need are some early points and a bit of luck."
Paul Fleming replaces Henry Goodburn on the wing as members of Heath's table-topping second team continue to stake claims for National League places.
Flanker Dave Wattam returns to the pack.
Worthing are at home to Camberley, who went down from National Three South last season.
The Surrey club have struggled since, though, currently standing second from bottom in London One while Worthing are mid-table.
Ben Dudley, formerly with UC Chichester, gets a debut in the Worthing back division with Terry Butler unavailable.
Lock Charlie McGowan has a fitness test on an arm injury but Mike Imrie and Raynn Bruce definitely return.
Coach Ian Davies said: "All the reports I hear from Camberley are that they have a very good back three and a few sevens players in their side.
They will also be muscular up front so it will be tough."
Lewes's home game with Chichester in London Three South East should indicate which of the county's more senior clubs have a decent chance of promotion this season.
Bognor and Brighton are both at home chasing their first points of the season.
After a series of narrow defeats, Bognor are desperate to beat both and Tonbridge Juddian and Brighton in the next eight days but they have been hit by the departure of flanker Jonny Lang on a year-long trip to Australia.
Skipper Karl Flynn said: "It's a very big loss for us. He's one of our top players."
Versatile Phil Hastings gets first crack in the vacant No. 6 shirt.
Crawley could not choose a better time to score their first win of the London Four South East campaign as neighbours East Grinstead visit.
Gs are coached by former Crawley man Steve O'Reilly.
Crawley team manager Geoff Lodge declared: "We will be completely focused and determined to kick-start our league campaign."
Three Sussex One teams still boast perfect league records.
Of that trio, Heathfield and Waldron look to have the toughest test in prospect tomorrow as Burgess Hill visit.
