Meanwhile, the Tigers are set to promote Brad Miller and Addam Maric from the rookie list, with both a chance to play in Round 1 against Carlton.
Hardwick indicated the pair of Melbourne rejects were likely to be rewarded for impressive pre-seasons.
Defender Kelvin Moore and young forward Dean MacDonald are on the long-term injury list, allowing the Tigers to elevate two replacements.
"We have been really pleased with the way Brad and Addam have applied themselves this pre-season," Hardwick said.
"They have worked hard on and off the field, and obviously put themselves in contention for a place on the senior list."
Maric, 21, has been a surprise packet, while Miller, 28, who played 14 games for the Tigers last season, continues to impress as a third tall forward option.
