Panesar place 'not set in stone'
Panesar showed impressive control on day one in Adelaide
Coach Duncan Fletcher says England may review Monty Panesar's place because of the loss of Marcus Trescothick. England's line-up for the final warm-up game was supposed to be their side for next week's the first Ashes Test.
But Ashley Giles' batting ability may still count in his favour after Trescothick left the tour on Tuesday.
"We wanted Monty if Trescothick was there, because Trescothick added [batting] depth. Now, we might have to re-think it," Fletcher told BBC Sport.
Current venue Adelaide is more of a batting-friendly surface than Brisbane, where the first Test begins on 23 November.
Brisbane is considered currently the fastest wicket in the country, confirmed by Australia's decision to pick just one spinner in their 13-man Test squad.
The major factor is to see what the balance of the side looks like Duncan Fletcher
England also look likely to go with four pace bowlers, including all-rounder Andrew Flintoff, and a single spinner.
Giles has not played Test cricket in a year, having undergone three operations on his hip, but offers a better batting option at eight in the order.
Panesar has taken 32 wickets in 10 Tests since then and is seen as the more attacking option.
He showed impressive control in bowling 22 overs on Friday, conceding just 54 runs for one wicket.
"We're not going to say that side is cast in stone," Fletcher explained.
"The major factor is to see what the balance of the side looks like."
Fletcher also confirmed that Paul Collingwood, who stepped into the side in Trescothick's absence, would take his place in the slip cordon.
"Collingwood has fielded in the slips for Durham so he will field third slip when Fred [Flintoff] isn't bowling and second slip when he is," he added.
England wait on Harmison fitness Coach Duncan Fletcher has admitted England do not know if Steve Harmison will be fit for the first Ashes Test. Harmison, who has a history of back trouble, was left out of the side for their final Ashes warm-up match after waking up with tightness in his side.
"It's similar to the one he had during the summer, which just irritated him, although he could bowl," said Fletcher.
"He's had a scan, which was pretty inconclusive. They have given him an injection and he says it has improved."
Harmison missed the one-day series against Pakistan in the summer with an injury described as being to his lower back (which could bring side pain) but returned for the ICC Champions Trophy.
"We will just see how he [does] in the morning and if he's fine we'll try and bowl him in the nets," Fletcher told BBC Sport.
Lancashire seamer Sajid Mahmood replaced Harmison for the warm-up game and went wicket-less on day one.
But the England coach was impessed by the performance of England's three senior seamers, who shared five wickets.
Matthew Hoggard took three wickets in 12 balls and James Anderson shared the new ball with him, dismissing former Test batsman Matthew Elliott.
"The morning session was as good as I've seen England bowl for some time - there was good discipline, good control and they didn't lose their concentration," Fletcher added.
