Adelaide veteran Tom Lynch has finally succumbed to a toe injury and will miss Saturday's AFL clash against GWS.
Lynch has played sore for the past month but Crows coach Matthew Nicks says he's been forced to rest the 158-gamer.
"Unfortunately we couldn't get him to train again," Nicks told reporters on Friday.
"It's a tough one because it's inflammation, it's not necessarily one where we know a timeframe on ... .this is one of those situations where we don't know exactly how long (out).
"We hope a week will help him and the inflammation and pain will die down. We'd love to get him to a point where he can play unassisted."
Nicks said he had no regrets over using Lynch as a medical substitute in last week's loss to Hawthorn.
Lynch's use sparked debate, with the 30-year-old taking about 15 minutes to get ready to play when defender Will Hamill copped an ankle injury.
Hamill will also miss Saturday afternoon's Adelaide Oval fixture against the Giants, with fellow backman Luke Brown also in doubt.
Nicks said Brown was battling a couple of issues - his absence would rob Adelaide of it's preferred match-up on Giants star Toby Greene.
"I know Toby really well and and there's a plan ready for him," said Nicks, a former GWS assistant coach.
"It's a matter of whether that plan is going to work.
"He is a very talented footballer ... he has been very much the barometer of where they have been at.
"He is very dangerous ahead of the footy ...we have got a couple of plans in case the first one doesn't work."
Nicks said his Crows, in ninth spot with three wins, had the utmost respect for the Giants, who have won two of their past three games to sit in 14th place.
"I know them reasonably well and sometimes that is harder as a coach because you know what they can do," he said.
"They're a pretty good outfit.
"They have got a lot of talent in that side, they're playing some really strong footy at the moment with a young group, it's a credit to them."
