Essendon could welcome back Jayden Laverde and Ned Cahill this weekend, with the fit-again forwards set to put their hands up for selection.
Laverde has been sidelined since suffering a syndesmosis injury in the round eight win over Adelaide, while a minor quad injury put first-year player Cahill's promising progress on hold.
Head of medical services David Rundle said this week's main session would determine the pair's availability.
"Jayden's going very well. It's now six weeks since he had syndesmosis stabilisation surgery. He had a solid training session on the weekend and he'll train fully with the group this week. Provided all goes well in our main skills session later in the week, he'll be available to play this week," Rundle said.
"Ned's going very well. It's just over three weeks since he injured his quadricep. He had a solid training session on the weekend with Jayden, and he'll integrate fully with the group this week. Provided all goes well following our main skills session, he'll be available to play as well."
Aaron Francis and Tom Bellchambers are also chances to return this week from hamstring tendonitis and knee pain respectively, but will need to prove their fitness in main training.
The Bombers will make at least one forced change for their clash with Port Adelaide on Saturday, with dynamic forward Irving Mosquito rupturing his ACL at the weekend.
Rundle said the 20-year-old would undergo a knee reconstruction in the coming weeks.
"An MRI confirmed that Irving ruptured his ACL. There was some associated bone bruising, which is common with that particular injury," he said.
"He'll have reconstructive surgery in the next couple of weeks, which will give the knee time to settle down before he goes into that operation."
Essendon will name its line-up to face the Power at 6:20pm AEST on Friday.
