Matt Peters travels back from Exeter University to provide some extra aggression in the pack for Portsmouth’s visit to Cobham in London one south.
Peters replaces the injured Will Brock in the only change from last week’s crucial win over Haywards Heath.
The win took Portsmouth out of the relegation zone.
And coach Ian Chandler expects them to climb further away from the bottom.
‘We are looking to repeat last season’s comfortable win at Cobham,’ he said.
‘After last year, we know all about their small pitch and what to expect.
‘We scored three good tries in our last game and will look to take the game to Cobham.’
Portsmouth: Duffus, Gronow, Richards, Barnes, Carpenter, Neville, O’Connor, Cripps, Houlihan, French, Crabb D, Richardson, Peters, Long, Crabb J, Sargent, Bowen, Chandler.
n United Services are expecting a tough battle up front against Ventnor in Hampshire one at Burnaby Road (3pm).
‘Ventnor have a big strong pack and whoever wins the forward battle will probably come out on top,’ said Services coach Simon Burns.
‘If we get enough ball then we have the three-quarters to do them some damage.’
The home side are boosted by the return of experienced outside-half Wayne John.
‘Cowboy (John) has played at a high level and he organises the other players around him,’ said Burns.
Veteran Burns settles for a place on the bench.
United Services: Hoskins, Bentley, Cantwell, Willoughby, Flyn, John, Irvine, Humberstone, Davis, Lanigan, Bell, Little, Baltrukenas, Guyll, Jonker, Burns, Smith, Bodel.
n Southsea Nomads can climb out of the bottom two by beating mid-table Romsey at Furze Lane, while Petersfield host Millbrook in an attractive game at Penns Place.
n Fareham Heathens will close the gap on the top two in Hampshire two if they overcome Lymington Mariners in the New Forest.
