Swindon will be aiming to keep the pressure on leaders Drifters in their Berks, Bucks & Oxon Premier campaign when they travel to lowly Harwell tomorrow.

The Greenbridge Road men are forced into a number of changes for the short trip into Oxfordshire, with injury problems to three club hookers.

Prop Nick Brooks steps into the No 2 jersey for the first team, with flankers Tom Loukes and Ian Butcher switching positions in an otherwise unchanged pack.

Nathan Waite, whose wife is expecting their third child, steps down this weekend, with James Turney returning to the Swindon midfield and Guy Sturla coming in at full-back.

Elsewhere, Robin Haxton switches to the wing, with Nathan Warren moving to the bench.

Also in the Berks, Bucks & Oxon ranks, Swindon College Old Boys will be hoping to preserve their 100 per cent record in Division 1 South.

Having won five out of five league outings, they travel to Chinnor's third string.

Their latest win came last weekend with a 37-0 success over Beaconsfield 2nd.

Captain Greig Evenett and Darren Johnston grabbed two tries apiece, with other touchdowns coming from Mark Lea and Kevin Mangell. Lea and Ben Robinson kicked the balance of points.

Wootton Bassett, meanwhile, will be looking to steal a march on Dorchester in their top-table Southern Counties South encounter tomorrow.

Bassett and Dorchester are one of four teams trailing leaders Frome by two points, and, despite facing a tough task, the Wiltshire side will be keen to turn over the Dorset side on their own ground.

Bassett's second string are also unchanged and at strength for what promises to be a tough Combination match against local rivals Chippenham.

In Dorset & Wilts Division 1 North, Supermarine host Marlborough at South Marston and will be attempting to avenge their recent defeat in the Powergen Junior Vase,

Supermarine Blades, meanwhile, take on Trowbridge 3rd in Dorset & Wilts 2 North.

Over in Gloucestershire Division 1, Cirencester bid to continue their upturn in fortunes when they host Ashley Down Old Boys at their Whiteway ground.

Welcoming back a number of former players Rich Williams, Bernie Davies and Adam Seager among them they have now won three of their five outings and will start favourites against a side with just one win to their name.
