Toby Greene could be in trouble with the MRO for an off-the-ball strike on Reece Conca.

The hit left Conca on the ground, searching for breath, but he was able to play the rest of the match.

Greene was quiet last night with 14 disposals and a goal in the Giants’ 38-point win over Fremantle.

The MRO will determine whether the contact was low or medium impact. A low grade would result in a fine, while a medium would see him suspended for a week.
