Opening batsman Marcus Trescothick was forced to leave the field on the second day of the two-day match against Western Australia with a shoulder injury.

The team management said he would need a pain-killing injection before the end of the day.

"The injury does not affect his batting, only his fielding," a spokesman for the England team said.

"The injury had been troubling Trescothick for a while."

He insisted the Somerset left-hander would be fit for the three-day match starting in Perth on Monday.

Vaughan, Flintoff, Gough out

Trescothick's opening partner, Michael Vaughan, sidelined with a knee injury, is a definite non-starter for Monday's game.

All-rounder Andrew Flintoff and fast bowler Darren Gough are also out of action.

Flintoff has flown to Adelaide for intensive treatment aimed at helping him to recover from a hernia operation.

Gough is still undergoing rehabilitation after severe knee surgery, and is thought likely to miss the opening Test in Brisbane on 7 November.

Fast bowler Simon Jones is also far from 100% with a side injury.
