England paceman Stuart Broad will be rested for the first two one-day internationals against Australia.
The 27-year-old was England's leading wicket-taker and one of the few England players to emerge from England's humiliating 5-0 Ashes whitewash with any credit.
Broad's absence, along with that of James Anderson - who has returned home for his scheduled break - and Graeme Swann, means England will field an inexperienced attack early in the five-match series, which begins at the MCG on Sunday, shown live on Sky Sports from 2am.
Steven Finn is likely to lead the attack with Sussex paceman Chris Jordan and Chris Woakes also hoping to figure.
Finn didn't play any of the Test matches as he continues to struggle with his rhythm and he spent large parts of Friday's net session in consultation with coaches Ashley Giles and David Saker.
Eoin Morgan is confident Finn can iron out his problems and be a decisive figure in the five-match series as England look to salvage some pride from the tour.
"I haven't seen very much of him. This has been our first training session as a squad," he said.
"I know Finny has been working really hard in the Test team and hopefully he'll make contributions along the way in the one-day series."
Morgan is one of seven new players to join the touring party and the left-hander does not feel he has joined a squad divided following the fall-out from the Ashes defeat.
"Absolutely not," he said. "The guys are good. We've had six or seven fresh faces come into the side who have brought a lot of energy, including myself.
"The guys are chomping at the bit to get involved. We've had a bit of time off and young guys coming through are keen to score runs and take wickets.
"A lot of guys are excited to get this series started.
"There's about 400 days before the World Cup starts and it starts here in Melbourne," he added.
"It's really exciting and the platform we build here during this series is really important.
"It's important that we do learn from any mistakes that we do make, and build confidence down in this part of the world."
