Adelaide defender Kyle Hartigan will not return to action on the MCG on Saturday after injuring his hamstring against Carlton.
Hartigan tweaked his hamstring early in the contest against the Blues before feeling his hamstring again in the third quarter.
Hartigan has played every game for Adelaide so far in 2017, and hasn't missed a game for the Crows since round one, 2016.
Adelaide will update Hartigan's fitness after the match.
