Mariners' Simon rushed in for Australia's all-or-nothing Beijing date
The Olyroos need to defeat the Ivory Coast tonight to progress past the group stage but will have to do so without their best attacking player.
"There should be no issue with getting it done in time, itâs simply a case of waiting for the relevant processes to unfold," a team spokesman told Foxsports.
"Archie has been seen by the FIFA doctor on site and the reports and his scans have to go to the FIFA and the AOC medical commission. We hope to have confirmation from them tonight.
"Then the AOC have to manage the process of getting Matt accredited but hopefully it will be fine."
