Collingwood president Eddie McGuire and North Melbourne chairman James Brayshaw are expected to speak out on Monday after the AFL slammed the pair for their part in an inappropriate conversation about Fairfax journalist Caroline Wilson.

The conversation, which took place on-air on Melbourne radio station Triple M on the Queen’s Birthday public holiday, also included All Australian selector Danny Frawley, journalist Damian Barrett and Kangaroos legend Wayne Carey, although the latter pair weren’t admonished by the AFL for their part in the exchange.

Speaking to Triple M shortly before he took part in the Freeze MND charity slide event at the MCG, McGuire suggested Wilson should be the only participant in next year’s charity ice slide, which dunks selected celebrity sliders into an ice-filled pool to raise funds for motor neurone disease research.

In a week where the Pies were awarded a licence to field a team in the new women’s national league, McGuire said he would pledge $50,000 “if she stays under”, before going on to describe Wilson as “like a black widow” spider.

“AFL chief executive Gillon McLachlan tonight said he contacted club presidents Eddie McGuire and James Brayshaw late today regarding an on-air radio discussion they had been a part of before last week’s round 12 Melbourne v Collingwood match at the MCG,” an AFL statement issued on Sunday read.

“Mr McLachlan said the AFL had only become aware of the matter today, in which a group discussion before the Freeze MND event at the MCG had referenced senior Fairfax Media journalist Caroline Wilson in a disparaging manner.

“Mr McLachlan said the AFL had expressed the strong view to both club presidents, and All Australian selector Danny Frawley … that although seeking to be light-hearted, the language and tenor of the wording could be seen to be supporting violent attitudes or actions against women, and was therefore clearly not appropriate.”

Brayshaw said he would pledge money in reply to McGuire’s comments.

Frawley apologised for his part in the conversation in which he said, ‘I’ll actually jump in and make sure she doesn’t (surface) – I’ll hold her under”.

“Last Monday on radio I made a couple of insensitive and inappropriate remarks about Caroline Wilson,” Frawley said on Fox Footy.

“Clearly it was a poor attempt at humour for which I sincerely apologise.”

The Western Bulldogs-Geelong game on Saturday night supported the White Ribbon campaign to prevent violence by men against women.
