England move on without Jonathan Trott
England arrived in Alice Springs following Jonathan Trott's departure for this week's two-day fixture against a CA Chairman XI at Traegar Park, but they will also have to do without Tim Bresnan for the match.
Trott - described as a "rock" for England in recent years by coach Andy Flower - had to leave their Ashes tour on Sunday night because of a stress-related illness.
There are no immediate plans to replace him, leaving a new battle to ensue for England's vacant number three spot in next week's Adelaide Test - when the tourists need to fight back from a 1-0 deficit after the crushing 381-run defeat at the Gabba.
Ian Bell and Joe Root are the obvious candidates for a move up the order, from numbers five or six respectively - while young Yorkshiremen Jonny Bairstow and Gary Ballance will be in a three-cornered contest with Ben Stokes to slot into the middle order.
Ballance and Stokes are uncapped at Test level.
Bresnan, meanwhile, is set to play for the England Performance Programme team in a three-day match against Queensland 2nd XI in Brisbane - starting on Wednesday - to try to demonstrate his recovery from a stress fracture in his back, and therefore his readiness for Adelaide if required as the third seamer.
Flower has been at pains to stress Trott's importance, but equally the opportunity which has therefore arisen for an aspiring batsman.
"He is an excellent team man - and as a quality international batsman, he has been a rock for us over the years since 2009," Flower said of Trott.
"He will be missed. But it opens up an opportunity for one of our young players to come in, and that's very exciting in a way.
"I'm sure the young player who gets the chance will be absolutely champing at the bit to show what he can do in international cricket."
England flew in and out of Alice Springs - they will return on Wednesday, to begin preparations for the tour match starting on Friday - and have travelled on to the tourist attraction and sacred site of Uluru.
On their return, Flower and captain Alastair Cook will begin to figure out in earnest whether Root or Bell is promoted.
Of the latter, Flower said: "I would agree ... moving around the order might not be ideal.
"But then the Trott incident, we could not foresee that.
"Root played superbly towards the end of that (first) Test - he showed what a good, young, mature man he is and a very fine player.
"So he would be capable of doing that.
"We haven't made that decision yet."
Cricket Australia CEO James Sutherland and Australia coach Darren Lehmann both sent messages of support to Trott.
Sutherland said: "All the staff, management and players at Cricket Australia wish Jonathan Trott well. We hope to see him fit and healthy and back on the cricket field soon."
Lehmann used Twitter to say: "I wish Johnathon Trott a speedy recovery from a tough situation, a safe flight home to be with family!"
