Andrew McDonald admits he has concerns over Cameron Green's workload, indicating he would like the allrounder to keep an open mind about playing in next year's IPL.
Green has nominated for this month's auction, where the allrounder is expected to fetch big money as one of the world's best emerging talents.
The 23-year-old has spoken with Australian officials about his workload through next year, with the IPL sandwiched between the Border-Gavaskar Trophy in India and the Ashes in England.
David Warner last week warned Green about the workload challenge, with his stint in India to be as much as 19 weeks before a World Cup in the country later in 2023.
McDonald encouraged Green to nominate, but said any decision on whether the West Australian follows through and plays should be made closer to the date.
"His overall load in the next 12 months of cricket, is it a concern? Yeah I think it's a concern for every player," McDonald said.
"We've spoken about it several times. it's a hypothetical to see how he's feeling come the end of March.
"He's got a lot of cricket before the IPL and I'm sure his decision won't be made right now, it will be made later on down the track leading into the IPL.
"You never know what your body is going to feel like in three months' time on the back of nine Test matches plus some white ball cricket of the back end of that Indian series.
Green's situation comes after Pat Cummins pulled out of his rich IPL deal last month, citing Australia's busy schedule.
Mitchell Starc has long skipped the tournament to spend time at home and ensure he is fit for Australia, while Josh Hazlewood has said he will wait until closer to make a call.
All three of the quicks are also uncontracted for this summer's Big Bash League and they will miss the domestic tournament.
Green remains contracted to the Perth Scorchers and his workload has always been a topic of discussion.
Back injuries that plagued him through his late teenage years restricted him from bowling, with limits placed on him.
The allrounder was used for just 13 overs in the fourth innings in Perth on the weekend with Cummins injured, but McDonald said there were no more restrictions.
"We're lucky and fortunate enough that the quality in front of him doesn't mean that he has to bowl excessive amounts of overs," McDonald said.
"He bats in the top six, he's holding his own as a batter. So I could say that he's pretty much unrestricted at the moment."
