Beaten-up rookie Docker Andrew Brayshaw is not friends with assailant Andrew Gaff, did not play golf with the suspended Eagle and his family are not okay with the vicious derby attack that left the 18-year-old with a broken jaw and three displaced teeth.

West Coast chief executive Trevor Nisbett on Monday painted a picture of having a pleasant relationship with the Brayshaw family, whose son Hamish plays for the Eagles.

"It is an extremely unusual circumstance. Five days ago the three of them were on the golf course together," Nisbett said on Monday. "They have a genuine friendship."

But Brayshaw's older brother Angus, who plays for Melbourne, said his family were very upset at Gaff and he was unsure why Nisbett had told a packed media conference about a golf game that didn't include Andrew.

"I’m not sure how it’s been miscommunicated or who’s said what to who,” Brayshaw told the AFL Exchange podcast.

"They didn't play golf, Hamish said he wasn't sure where they (West Coast) got that from."

In contrast to Nisbett's comments, Angus pointed to his family being livid about the incident and hinted his family could take the matter further if the AFL Tribunal didn't come down hard on Gaff, who's out of contract at the end of 2018 and unlikely to play again this season.

"Imagine if this has happened at a nightclub or on the streets, it's an assault," Brayshaw said.

"I'm not a lawyer … but you could probably get in jail for something like this, I would imagine. The one-punch thing has been a huge campaign.

"I just can't believe, honestly, that it's happened. I'd be really upset if he gets less than seven (weeks). If it's anything less than seven, someone should do something about it.

"I can't see how Andrew Gaff can play football again this year.

"Hopefully it is sorted out by the tribunal and then we can move on from it."

Despite surgery and being ordered to eat no solid foods for four weeks, Angus said his brother wasn't out of the woods with the injuries he sustained from Gaff's callous punch to his face in the third quarter of Sunday's match at Optus Stadium.

"He's battling at the moment with what happened," Brayshaw told AFL Exchange. "He's had a few little things he has had to work through. He had surgery that night, issues with his teeth seeing a dentist a bit [and a] sizeable chunk of his lip is in trouble. I wish I could be over there with him. It's a terrible thing he's had to go through.

"Obviously his health is at the forefront of everyone's mind and hoping he's okay in the long term.

"It's a pretty grim outlook at the moment."

Angus also took a swipe at people sticking up for Gaff's good character.

"People say he'd never do anything like this, and character references are a thing in the tribunal but from what I can see ... I'm watching this thing, he's squared up to him," he said.

"As far as I can see, he's looking at him and then just absolutely ruined Andrew's mouth with his fist.

"He's an 18-year-old kid and there's no way Andrew would've done anything to warrant a punch in the face, not that anything warrants that.

"I mean he's a first-year player, it's just ... it's such a grim, grim thing to have happened. I just can't believe it to be honest."

The young Melbourne star also spoke of the pain at not being in Perth to be with his brother and said his mother in particular was struggling with the fallout.

"It was a pretty grim night, and one I won't look back on too fondly," Angus said about finding out the news on Sunday evening.

"It was really hard, it was good that mum and dad were over there.

"Mum is definitely upset. I just felt a bit lonely, I just wish I was there with everyone.

"It's been hard to separate the emotion from it. My brother being at West Coast as well, has made the whole situation weird.

"I'm sure Hamish would just want to be sticking up for his brother."

The Eagles were also criticised for shielding Gaff from a throng of media when he arrived in Melbourne for his hearing on Tuesday night.

"He's not a politician, he's not a rock star, he's a footballer," AFL Exchange broadcaster Cal Twomey said.
