Alex Silvagni is handed a four-week ban for a high hit on West Coast's Jamie Cripps.
Silvagni - whose case was referred directly to the Tribunal by the Match Review Panel on Monday - pleaded guilty as charged, with his strike graded as high impact and high contact.
In his evidence, Silvagni said Cripps had moved into his path to stop him pursuing his opponent, and he had responded by attempting to "move him out of the way" with a "strong, forceful" bump.
"I didn't mean to strike him in the head," a contrite Silvagni said.
"It didn't sit with me well at the time, during the game or still now. As a footballer I don't like seeing it and I didn't mean to do it.
"I just want to publicly apologise to Jamie for the incident on the weekend. It's not something I stand for.
"I still feel a little ill from it from the weekend. It's definitely not something in my character. I'm deeply remorseful for the incident."
Jamie Cripps could be available for West Coast's clash with the Western Bulldogs after scans cleared him of a fractured jaw.
Cripps copped a nasty elbow from Dockers defender Alex Silvagni in last Sunday's Western Derby and the Eagles feared he might have suffered a fracture as a result.
But scans have cleared Cripps of any structural damage.
West Coast football manager Craig Vozzo told the club's website that Cripps was still suffering headaches from the incident and he would be monitored this week.
"Jamie obviously suffered that pretty nasty knock on the weekend, but going through the x-ray process, it's revealed no break which is terrific news for us and more particularly Jamie," Vozzo said.
"He was dazed a little and he's still having headaches, so he'll be a test later in the week."
