Adelaide forward Mitch McGovern will visit a specialist during the week to determine the extent of a hamstring injury suffered during Saturday night's showdown.
Scans over the weekend revealed McGovern suffered a "significant amount of damage" to his right hamstring, and will now be looking at a recovery time of between 10-12 weeks should the injury require surgery.
"Unfortunately, scans have revealed a fairly significant amount of damage," Adelaide High Performance Manager Matt Hass told theย club website.
"Across the rest of this week, weโll consult specialists and come up with a plan of action.
"Itโs fair to say, he will spend a period of time on the sidelines."
The 22-year-old will likely be replaced in the side by returning forward Josh Jenkins, who missed the Showdown after a rib injury suffered in the round two win over Hawthorn.
"At this point, the cartilage is causing [Jenkins] the most grief," Hassย said.
"Weโll continue to assess him day by day and do everything that we can to get him up for the weekend."
