FILL-IN Richmond captain Jack Riewoldt is set for another stint on the sidelines, with a right knee injury spoiling his return to the field on Wednesday night.
The Tigers' injury woes continued when Riewoldt left the ground for good early in the last quarter, after a wrist problem kept him out for the previous three matches.
"It's his right leg, so his good leg, (and) it's a PCL-type injury. We're not exactly sure of the extent of that but he'll miss some time, unfortunately," Hardwick told reporters.
"How long that is, we're not exactly sure. We'll get some scans obviously done pretty quick, but it's disappointing.
"He's worked incredibly hard to get back, and then to hurt his other knee … is really disappointing, so we're hoping for the best but he'll obviously miss some footy."
