Salter was cleared to return to football by club fitness staff on Wednesday after suffering a foot fracture during the pre-season.
He will play for aligned SANFL side Woodville-West Torrens this weekend, initially in the reserves.
But his recovery from long-term injury means Kane Mitchell - the rookie who was upgraded to replace him for the first three rounds of the season - will be placed back on the rookie list.
Mitchell has been the substitute for Port Adelaide in its first three wins of the season and impressed pundits with his hard-running attack on the ball.
While he was disappointed to be taken off the senior list, Mitchell says it is great news for Salter to be cleared of injury.
"It's great to have Salts back - he's a great guy, a great player and I'm looking forward to playing with him in the SANFL,” Mitchell told portadelaidefc.com.au.
“Now I’ll go back to the Eagles and continue to train hard and hopefully I'll earn the next upgrade.
Both Salter and Mitchell will play for the Eagles – the former trying to press for selection while the latter works hard to earn promotion back to the rookie list midway through the year.
All AFL clubs are permitted to upgrade one rookie to the senior list after Round 11.
