On his return from a two-week hamstring lay-off, Hickey sprained an ankle during the second quarter against Melbourne last Friday night.
After being helped from the field, he was able to return for the critical battle against Max Gawn as the Eagles surged home to clinch a 16-point victory.
However, the 28-year-old will miss the Crows trip and is doubtful to be available to face the Western Bulldogs in round 11.
