Port Adelaide's Danyle Pearce says Western Bulldogs' ruckman Will Minson's comments about Pearce's mother were offensive and should not be tolerated.

In response to the Bulldogs' announcement yesterday that Minson would be banned by the club for one AFL game, Pearce released a statement saying Minson needed to start thinking about improving his on-field behaviour rather than worrying about handing out apologies.

Minson fronted a media conference at Whitten Oval offering his apologies and saying he had no excuse for his actions in Sunday's round-12 clash at Etihad Stadium.

Minson said he had made unsuccessful attempts to contact Pearce.

''I accept the course of action the Western Bulldogs have taken,'' Pearce said. ''The important thing for me is that Will understands that this is not a minor matter that can be brushed under the carpet. It is a very big thing and insulting a player's family is just not acceptable.

''He needs to know there is a line that you shouldn't even contemplate crossing. Will has apologised, but I don't need that to move on. His actions from here will mean far more than words.''

Port Adelaide chief executive Keith Thomas noted Minson had apologised to the club in 2008 for making on-field comments to onballer Kane Cornes about his ill son.

''Whilst it's the second time we have faced a similar situation, we take Will's apology on face value and trust it won't happen again,'' he said.

Minson said he was very sorry for what was said on the field.

''The last 24 hours have been an extremely stressful period for myself and no doubt unnecessarily stressful for Danyle Pearce and his family and the Port Adelaide Football Club,'' Minson said. ''I have absolutely no intention of putting anyone through that sort of stress or attention ever again. What I said on the field, I am very disappointed about that. My comments were inappropriate.''

Minson choked up and was unable to answer at one stage when asked if he could redeem his reputation.

''That is certainly what I'm going to be dealing with for the rest of my life and it's important I learn from this experience,'' the 27-year-old said.

''People are going to form their opinions either way. I have no control over what people say or think about me. My younger brother spent three years at Port Adelaide and he speaks very highly of the footy club and of the players.

''Hopefully I haven't done anything to affect Hugh's relationship with the football club.''

Asked if his version of the incident differed to Pearce's, Minson said there was no need to go into the details of what was said.

Minson will miss Saturday's game against Brisbane at Etihad Stadium.

Port captain Dom Cassisi said the two worst things he has heard on a football field have come from Minson.

''Once you start involving, whether it'd be your mother, women, your race or kids or whatever, I just think it's crossing a line that doesn't need to be crossed,'' Cassisi said.

AFL football operations general manager Adrian Anderson said the league endorsed Minson's suspension. AAP
