ADELAIDE midfielder Brad Crouch will miss at least two weeks with a hamstring injury.

Crouch, 22, didn't play against Richmond in round three.

Crows fitness coach Matthew Bode said the club will be conservative with Crouch.

"Brad has a minor hamstring issue," Bode told the club's website.

"We’ve always taken a cautious approach with Brad.

"He’s expected to be out for about two to three weeks."

Hawthorn and Fremantle are Adelaide's next two opponents.

Wingman Paul Seedsman may be available to play against the Sydney Swans this Saturday night after being concussed early in the final term against the Tigers.

"Paul had a slight concussion," Bode said.

"He’ll go through the normal procedure with the doctor this week and be assessed."

Curtly Hampton should be ready to play for Adelaide's next SANFL game, on Sunday, April 24. The Crows' reserves have a bye this week.

Hampton has been dealing with a foot injury.

Former Victorian cricketer Alex Keath and rookie Paul Hunter could both be available for that game.

It would be Keath's first game for the Crows, after completing a mini pre-season.

Hunter has had an ankle injury.
