Former AFL player Scott Cummings has been sacked by radio station 3AW over jokes he made about sexual assault on his Humpday podcast with former Collingwood star Dane Swan.

Cummings - who laughed while describing sex acts, including "sneaking up behind a girl who is on all fours throwing up" and sexually assaulting her - has apologised for the "disrespectful and wrong" comments and said he would step down from the podcast immediately to reflect and seek guidance from Domestic Violence Victoria.

Despite his apology, the radio station said it would terminate its relationship with him and he would not appear on 3AW Football again.

But his co-host Swan remains defiant, shrugging off all criticism and going so far as to say he will be back "funnier and worse than ever".
