Doubt hovers over Crows' Brodie Smith

Adelaide's All Australian backman Brodie Smith has yet to convince coach Don Pyke that he has overcome a hamstring niggle.

Pyke says Smith will have further fitness tests to determine if he'll play in the AFL clash with Fremantle on Saturday night.

"Brodie has got a little bit of work to do in the next couple of days," Pyke told reporters on Wednesday.
