Adelaide defender Josh Worrell will spend a stint on the sidelines after suffering a hamstring injury against Fremantle last weekend.
The injury hampered Worrell's evening in Perth, with the setback adding to the youngster's recent battle with a hamstring strain.
Adelaide's high-performance manager Darren Burgess described the ailment as a "reaggravation" of a prior injury and didn't set a timeline for Worrell's return to play.
"The scans showed some damage but because it's a reaggravation of the hamstring injury he suffered last month, it's difficult to put an exact timeframe on his return," Burgess said.
"Josh has started the rehabilitation process and his return to play will be dependent on how the injury responds to treatment."
The versatile Worrell, taken at the 2019 National Draft with Pick 28, played the final four games of the Crows' 2022 season after a promising campaign in the SANFL.
Worrell managed an average of 14.2 disposals across his four AFL contests last year after only playing one game in 2021.
The Crows face West Coast this Friday before clashing with the GWS Giants in Round 1.
