Oxford Harlequins are forced by injury to make two changes to the pack for their South West 1 trip to Keynsham tomorrow.

Their New Zealand second row Elliott Stephenson suffered a fractured cheekbone and a broken eye socket during their home defeat by runaway leaders Reading last week, and could be out for the rest of the season.

However, Quins have plenty of strength in the lock department and experienced players Rob Dow and Simon Chatterton are vying to take his place.

Prop Will Houston injured a knee in that game, so in the continuing absence of Jon Silversides with a back injury, he will be replaced by Paul DeLange.

Chris Ashton is added to the squad and will compete with Jim Anderson for the open-side flanker's position.

Henley coach Nigel Dudding makes just one enforced change for their tough National League 1 match at home to high-riding Pertemps Bees, formerly known as Birmingham/Solihull.

Jeff Atkinson is not available for the next two weeks as he will be in Australia. This means that Matt Payne will come back into the squad

The Hawks go into this match having risen to tenth place in the league following the win against Manchester - the first time they have been out of the bottom three since October.

In the absence of the injured Andy Smith and James Shaw, the versatile Dave Engwell switches to scrum half for Oxford's match at home to Milton Keynes in Berks, Bucks & Oxon Division 1.

Oxford include three brothers in Jonathan, Mark and Adam Viner.
