"If he drops out of the ODI team then there's a possible lack of momentum there.
"There are three Test matches in the West Indies (in April), then as I understand it there are no more Test matches until October or November.''
Ponting's 13,704 runs at an average of 42.03 in 375 ODIs ranks second only to Sachin Tendulkar, while his 13,200 runs over 162 Tests makes him the third highest run scorer in Test history.
Inverarity described Ponting as a gem of a human being, and said the Tasmanian took the news of his dumping "on the chin''.
But he added the decision to axe Australia's finest player since Don Bradman was a unanimous one.
"You don't put your heart to one side, but the head has got to dominate,'' Inverarity said of Ponting, who captained Australia to World Cup crowns in 2003 and 2007.
"In elite sport, there's no place for sentiment.''
In other big team news, Inverarity confirmed Matthew Wade had officially taken over from Brad Haddin as Australia's preferred ODI wicket-keeper.
Meanwhile, skipper Michael Clarke is on track to make his return from a hamstring injury against Sri Lanka at Bellerive Oval on Friday after being named in Australia's 13-man squad.
But fit-again allrounder Shane Watson, who also earned inclusion, is more likely to return against India in Sydney on Sunday.
In the other change to the squad, paceman Ryan Harris replaced Mitchell Starc.
Australia's squad to play Sri Lanka in Hobart on Friday and India on Sunday in Sydney: Michael Clarke (capt), Shane Watson, Dan Christian, Xavier Doherty, Peter Forrest, Ryan Harris, Ben Hilfenhaus, David Hussey, Michael Hussey, Brett Lee, Clint McKay, Matthew Wade, David Warner.
