Chinnor fly half James Cathcart faces a spell on the sidelines after dislocating his shoulder in training.

Cathcart, who has been the club's first-choice kicker, was taken to hospital after the injury on Tuesday night.

Ben Hewitt is set to to take over kicking duties for tomorrow's National 3 South clash with Rosslyn Park at Kingsey Road.

Chinnor coach Jason Bowers said: "It happened in the last play of training.

"James just got caught in the wrong position and we had to dial 999.

"He will be OK and the good news is that there is no serious damage.

"It will mean a reshuffle of our backline, but if you lose a good player it's nice to have another to fill in."

Youngster Joe Robinson replaces Cathcart in the only change to the squad from Chinnor's last league game against Richmond.

Bowers used many of his second-team players in last week's 19-17 EDF Energy National Trophy victory over Lydney.

But he was never going to make big changes for tomorrow's game.

"It was always planned to be like that," said Bowers.

"Last week was fantastic, but it was designed to look at a few players for later in the season.

"It also gave many people the chance to rest after a tough start to the season."

Henley Hawks director of rugby Jason Forster should be selecting from strength for their home clash with Canterbury.

This is particularly true at scrum half where James Gaunt, Tom Hancock and Jack Shaylor are all vying for a spot.

Stean Williams should return at openside flanker, while Forster must decide whether to go with Dave Clements or Jack Hennings at No 8.

Clements impressed there last week, although he had been a regular at lock where Charlie Nixon and Steve Green looked strong.

London Irish hooker James Clark comes into the squad after joining Henley on loan.

Chinnor (v Rosslyn Park, home): from Winpenny, Whelan, Ellis, Cawston, Eckert, Hutchings (capt), Black, Hastings, Jackson, Jackman, M Williams, Prescott, Hewitt, Powell, Oxley, Brown, R Williams, Wallace, Serrano, Shiel, Robinson.

Henley Hawks (v Canterbury, home): from Smith, Haynes, Shaylor, Flammia, Baggett, Simmons, Davies, Turner, Gaunt, Hancock, Fuller, Gentilli, Milford-Scott, Tattersall, Matthews, Clark, Hoosen-Owen, Tuckett, Nixon, Green, Payne (capt), Williams, Hennings, Clements.
