Carlton captain Patrick Cripps was the only player to be charged by the AFL's Match Review Officer from his side's 17-point win over Collingwood on Friday, with a fine for rough conduct handed down to the Blues onballer.

A third-quarter incident involving Magpies defender Isaac Quaynor has led to the charge, with the incident graded as intentional conduct, low impact and body contact.

That assessment from the MRO has led to a $3,000 fine for Cripps, who can have the financial sanction reduced to $2,000 with an early plea.

The grading has also seen Cripps narrowly avoid a suspension, which would've occurred if the impact grading was viewed as 'medium' rather than 'low'. A 'high/groin' contact grading instead of a 'body' contact grading would have also led to a suspension.

The charge comes at a critical time in Carlton's season, with the win over Collingwood currently having them in sixth on the ladder with 10 wins from 19 games.

The Blues are on a six-game winning run heading into the last month of the home and away season as they look to make finals for the first time in a decade.

Cripps made his return from injury against the Magpies after a week off due to a corkie, while the club is sweating on results for midfielder Adam Cerra's hamstring injury that was sustained in the Round 20 win.

Carlton face fellow top eight side St Kilda next week before matches against Melbourne, Gold Coast and GWS.
