Sussex tackles Hampshire in the battle for a fourth round spot in the Powergen Intermediate Cup this weekend.
Four of the county's team have been drawn against sides from across the border.
They will be joined in the draw by Haywards Heath or Lewes while East Grinstead could also make it if they grab a win at London Scottish.
Brighton will be without their skipper Mark Jenkins for the home clash with New Milton and District.
The long-serving front row man broke an arm in a tackle during last week's crucial league win at Eastbourne.
New Milton are a rising force across the border, having recently hit the top of Hampshire One for the first time, and travel from the New Forest believing they can spring a surprise.
Roles will be reversed at Winchester where visiting Eastbourne will be the side with a chance of overturning league positions and scoring an away win.
Bognor skipper Karl Flynn rests his troublesome shoulder for the derby at Portsmouth.
Flynn will watch his new-look side with interest, notably in the centre where they have two Australians combining for the first time.
Martin Stock steps in at tight head to ease a props crisis.
Crawley complete the cross border clashes when they host Tottonians.
Rick Ure and Damien Lyall return to the Haywards Heath pack as rivalries are renewed with Lewes.
Gordon Denslow returns at hooker against his old club and there is a first real chance for summer signing Nick Stocker to shine in the centre.
Skipper Alex Meredith said: "We will not take this tie lightly. Lewes have always given us tough games."
Skipper and hooker Dave Hemsley (knee) is a doubt for Lewes.
There is also key league action as unbeaten Worthing stage a re-arranged clash with Wimbledon at Roundstone Lane.
Flanker Jamie Newhouse and full back Simon Swadling are away. Grant Gatford is named at hooker but he may revert to the back row if Jody Levett fails to recover from a gum infection.
Martin Eze makes a long-awaited return from injury on the wing allowing Tony Cruz to switch to full back.
Worthing coach Ian Davies has not been totally impressed by his side's recent form and expects a testing afternoon.
He said: "Wimbledon have turned their results around recently and everybody beat can everybody in this division."
Look out too for a host of cup ties involving the county's smaller clubs this weekend.
