Adelaide defender Tom Doedee has sustained a groin injury that is set to hinder his preparations for the 2021 season, placing him in doubt for the Crows' Round 1 clash.

Doedee's past two seasons have been riddled with injuries, limiting the 23-year-old to just the 10 matches across the past 24 months.

The key-defender suffered a season-ending ACL injury in the opening round of 2019 season and had his 2020 campaign cut short due to a hamstring complaint.

Doedee's 2021 pre-season is now facing a setback after sustaining a groin injury at training on Monday.

Speaking to football boss Adam Kelly revealed the extent of Doedee's latest complication.

"After appearing close to re-joining the main group, Tom has irritated the right groin which had been holding him back for the past fortnight," he said.

"He will be assessed during the week, after which we will have a clearer picture regarding his return to play date."

Doedee's absense adds to the growing list of casualties at West Lakes, with recruit Mitch Hinge also set for a spell on the sidelines after sustaining a dislocated shoulder.

"Pleasingly, scans have confirmed minor damage only, meaning surgery will not be required," Kelly said.

"He will be rehabilitated and managed conservatively back to full training. Over the coming week, we will be able to make a better assessment regarding expected return to play timelines.

"Thankfully, Mitch has completed a very strong pre-season and has a good foundation for the year ahead."

Adelaide are set to face Fremantle for their pre-season clash on Saturday, March 6 at Fremantle Oval.

The Crows will open their premiership season against Geelong at Adelaide Oval on Saturday, March 20.
