MATT Williams is under no illusions how pivotal Chinnor’s clash at fellow promotion contenders Old Elthamians tomorrow could prove to be in the run-in.

The Kingsey Road-based club are second, two points clear of their hosts, and travel to London in high spirits.

Chinnor are on a six-match winning run in National League 2 South and Williams hopes his side’s form continues.

The director of rugby said: “We’re heading into a big game.

“If they win, we drop down to third and it’s game on.

“If we win, they are over a game away from second and it just puts a nice little gap to the top at a very critical stage.”

Winger Luke Hibberd is injured (hamstring), prop Mark Darlington is away on international duty with the Netherlands, while lock Nathan Hannay is unavailable.

Josh Davies has returned to parent club Ealing Trailfinders due to an injury to their regular scrum half.

Henley Hawks travel to Clifton, hoping for a third win in a row.

Rob Bell, Tom Hall and David Hyde form a new back row, while hooker Stuart Philpott starts.

Oxford Harlequins eye a seventh win in eight games when they host Chippenham in South West 1 East.

Quins’ victory last week saw the Wiltshire side drop into the relegation zone and another triumph would further boost their chances of avoiding the drop.

Prop Matt Edney, centre Keni Fisilau and fly half Huw Dimond return to the starting XV.

Witney are without the injured George Lewis as they face Newbury Blues away from home.

Matt Clarke comes in at outside centre and Declan Bayliss keeps his place at No 8.

Banbury travel to Reading, while Grove take on leaders Old Patesians.
