Carlton midfielder Adam Cerra is free to face Adelaide after successfully downgrading his one-match striking suspension to a fine at the AFL Tribunal.
But the Crows will be without Mitch Hinge, whose one-game ban was upheld.
Cerra was suspended for striking Geelong's Jack Bowes in the third quarter of the Blues' win on Sunday.
The incident was graded intentional conduct, low impact and high contact, drawing a one-game ban.
Carlton first argued Cerra's action was not a strike - then, if it was a strike, they said it should be classified as careless rather than intentional.
The Blues were successful and it was downgraded to a fine, meaning Cerra can face the Crows at Adelaide Oval on Saturday.
Adelaide defender Hinge also fronted the tribunal on Wednesday, challenging his one-game ban for striking Fremantle's Andrew Brayshaw.
The MRO graded the incident in the second quarter of Friday night's match at Optus Stadium as intentional, low impact and high contact, leading to the suspension.
Hinge had argued he did not intend to strike Brayshaw, with the Crows hoping to have the incident downgraded to careless rather than intentional.
But the tribunal disagreed and he will miss a match.
North Melbourne confirmed they would not be appealing Paul Curtis's three-match ban for a dangerous tackle, which was upheld by the tribunal on Tuesday.
