The AFL tribunal on Monday night fined Greene $7500 after he pleaded guilty to serious misconduct against Western Bulldogs opponent Marcus Bontempelli.

While Greene is free to face Brisbane in Saturday's semi-final at the Gabba, he has now racked up more than $26,000 in fines and been suspended for six games.

Melbourne veteran Nathan Jones has paid out almost $28,000 in fines but has double Greene's tally of 143 career games.

Greene's latest penalty came after the AFL's legal counsel, Jeff Gleeson QC recommended a financial sanction was appropriate.

The tribunal jury was shown footage of Greene grabbing at Bontempelli's face and pulling his hair as they wrestled on the turf in the first quarter of Saturday's elimination final at Giants Stadium.

Gleeson submitted that Greene's conduct was "unacceptable", but conceded the footage didn't clearly indicate eye-gouging or scratching.

Greene briefly gave evidence, saying he had reacted excessively to what he labelled a dangerous tackle on teammate Brett Deledio.

"Looking back on the incident, I understand I overstepped the mark in my remonstration and I understand it's not a great look," Greene said.

"I apologise to Marcus if there's any harm done."

But he demurred when asked whether he would continue to play on the edge.

"I don't know, we'll wait and see what happens," he told reporters after the hearing.

Teammate Zac Williams earlier said while the Giants fed off Greene's niggling play, they needed to step up as a collective.

"We can't rely on Toby doing that every week," he said.

"With the Bulldogs (win), I think everyone turned up to play which was really good to see."

The AFL uses money collected through player fines to fund concussion research.
