WEST Coast ruckman Nic Naitanui doesn't want the AFL to introduce a send-off rule despite watching his teammate Andrew Gaff get knocked unconscious over the weekend.

Port Adelaide defender Tom Jonas is expected to be referred straight to the Tribunal for his crude forearm to the head on Gaff just moments after the Eagles midfielder had taken a mark.

Most lower levels of Australian Rules football have send-off rules for serious incidents.

Umpires coach Hayden Kennedy told AFL.com.au on Monday the umpires would be happy to hand out red cards if the AFL rules called for it, but Naitanui doesn't want to see the rule introduced.

"I don't think guys are doing anything too bad that warrants getting sent off," Naitanui said on Monday.

"I don't think it's in anyone's character. You don't have guys these days growing up to do that purposely.

"It was a late hit (on Gaff), and not something you want to see. But I'm sure the Match Review Panel will deal with it.

"I think it's probably worse that you stay on the field when you do something like that - because you feel pretty bad."

A host of Eagles players are expected to receive MRP fines for engaging in a melee following the hit on Gaff and Naitanui said it would be money well spent.

"I think the boys will be pretty happy paying the fines," Naitanui said.

"In the end you're not doing anything silly - you're just sticking up for your teammate.

"You'd probably get fined by the boys if you didn't go in."

Gaff will need to pass a concussion test if he is to play in Sunday's clash with Gold Coast at Domain Stadium.

But even if he is ruled out, the Eagles are expected to encounter few problems against a Suns outfit ravaged by injuries.

The Eagles finally broke their travel hoodoo with their eight-point win over Port Adelaide, lifting them back to within a victory of second spot.
