Four points clear at the top of London Division Two South, Portsmouth put their unbeaten record on the line against second placed Lewes tomorrow.

But a seventh victory of the campaign will put the Rugby Camp side in prime position at the helm going into the vital period of the season.

They are virtually unchanged again with just influential number eight James Pegler missing, so county flanker Brendan Treacey moves across and Dave Needham switches from hooker to the back row allowing new signing Matthew Lane to play in the front.

Gosport & Fareham, in fourth, make the difficult trip to struggling Wimbledon but the fact they are in the bottom two does not cut any ice with skipper Simon Burns who remembers the last two occasions his side visited the Surrey club.

"Wimbledon is a difficult place to go. Two seasons ago, we threw our promotion chances away there and last season we lost there again," he said.

Andrew Notley comes in for Gareth Slade-Jones at scrum-half and Barry McHardy keeps his place at hooker. New boy Ben Wyatt is given a start at prop.

l The encouraging win over Dings Crusaders last weekend has given Havant renewed heart but they must now show it was not a flash in the pan when they visit Tabard.

in National Three South.

They will field the same side with the exception of Neil McGovern - away with Harlequins Under-21 - so Owen Jones replaces him on the bench.

"Although last week was a great fillip to the squad, it means nothing if we do not go to Tabard with the same mental attitude and physical intensity," said director of rugby Adam King.
