Essendon forward Travis Colyer is set to spend the next three weeks on the sidelines after suffering inflammation in his right foot.
The Bombers have placed him in a moonboot to help him overcome the problem in his sesamoid bone, with high performance manager Justin Crow saying the club wouldn't be taking any risks with Colyer's injury.
"The sesamoids are a couple of little bones under your foot that can become painful. We want to settle that down, so we've got Trav in a boot," added Crow.
"He'll stay in the boot for three weeks now and he'll come out of that hopefully with the sesamoid settled and then he'll build back up again."
Colyer had his most consistent season for the club last season, playing 22 games and averaging 16.7 disposals per game.
The Bombers have better news over star defender Michael Hurley, who is ready to enter the next phase of his recovery after surgery on his wrist and hip at the end of the season.
David Myers and Matthew Leuenberger are both also tracking well after off-season finger and shoulder operations respectively.
Crow said of Myers: "We had that (finger) operated on and that hasn't affected David's pre-season at all. He's actually got in the majority of training both pre- and post-Christmas and he's in a really good place."
Leuenberger, who had his surgery four months ago, has worked through contact progressions in competitive training drills and elements of match play.
Jackson Merrett (broken leg) and Ben McNiece (neck) are back up and running, while young defender Jordan Ridley is a month away from resuming full training after having surgery on a syndesmosis ankle injury in December.
The Bombers are 4/5 to win their round one clash with the Adelaide Crows, who are 21/20.
