Australia are set to hand unheralded batsman Peter Forrest a debut in their Commonwealth Bank Series clash with Sri Lanka on Friday.
Coach Mickey Arthur revealed the 26-year-old, a shock inclusion in Australia's squad for the series, was likely to play at the WACA Ground in Perth.
"We do need to see Peter Forrest at some stage - but I'm not sure yet where he fits in," Arthur said.
"That is tomorrow's problem but it is likely Peter might get a go, but we still have to have a lot of discussion."
Forrest's inclusion in Australia's squad raised some eyebrows following his moderate return for Queensland in 50-over domestic cricket so far this season.
The right-hander has, however, caught the eye in the Sheffield Shield where he has made three centuries at an average of 54 this term.
Arthur refused to confirm who would make way for Forrest, although reports have suggested hard-hitting opener David Warner could be rested after his busy summer so far.
"Nobody wants to rest which is great, the guys want to keep playing and they realise we are starting to develop a really good talent pool now," he said.
"Places are at a premium and there are a lot of competition for places, which is perfect and it is right."
Australia kicked-off their tri-series campaign with a 65-run bonus-point win over India in Melbourne last Sunday.
Victory in Perth would already make the hosts firm favourites to reach the finals after Sri Lanka began their campaign with a four-wicket defeat to India on Wednesday.
