The tribunal is set for a bumper Tuesday night, with both Essendon skipper Zach Merrett and Collingwood vice-captain Taylor Adams to front up as well in a bid to overturn their respective one-match bans for dangerous tackles.
GWS gun Tom Green won't be involved after accepting his own one-match ban for a dangerous tackle.
The AFL is set to push for a ban of at least four weeks for first-year forward Caminiti after match review officer Michael Christian assessed his striking charge on Murphy as intentional conduct, severe impact and high contact.
The grading triggers an automatic tribunal hearing.
Vision shows Murphy forcefully pushing Caminiti in the chest during the final quarter and the St Kilda forward responding with a raised forearm that felled his opponent.
Murphy, who later had words with the Saints contingent on the boundary line, will miss the April 25 clash with Essendon as a result of his concussion.
Merrett elected to challenge his one-match ban for rough conduct over a dangerous tackle on Melbourne's Tom Sparrow.
The tackle was graded as careless conduct, medium impact and high contact, as were Green and Adams' respective incidents.
If Merrett and Adams are unsuccessful in overturning their bans, they will miss next week's Anzac Day blockbuster.
Last week, Hawthorn midfielder Will Day (two matches) and Geelong forward Gary Rohan (one match) tried and failed to challenge respective bans at the tribunal.
Gold Coast coach Stuart Dew and Sydney counterpart John Longmire said they'd told their players to refrain from taking their opponent to ground in tackles.
"It's almost at that point, isn't it, that if you choose to take a player to ground, if they hit their head, you're putting yourself at risk," Dew told Fox Footy.
"Which I think, by the way, is the right way to go, I think we need to protect the head as much as possible.
"So I think we do need to adjust our coaching, and there's far too many (dangerous tackles) in the first five rounds."
Longmire added he'd been part of an AFL forum several years ago where dangerous tackles were addressed.
"It was pretty clear from a coaching perspective, what we can do is tell our players in those situations when you can, is not take them to ground," he said.
