Fremantle coach Ross Lyon is adamant he doesn't want the third-man up ruck rule scrapped, but says the AFL faces an "uncomfortable" week in the wake of Aaron Sandilands' one-match ban.
Sandilands was suspended for making head-high contact to Ben Griffiths last week while the Richmond player attempted to go third-man up in a ruck contest.
Although there was no malice in the bump, the 11cm height difference between the pair meant shoulder-to-head contact was hard to avoid.
The Dockers are among the teams who regularly use the third-man up tactic at ruck contests, and Lyon doesn't want it banned.
But he said it was important for the AFL to come up with a way for ruckmen to protect themselves when they encountered such a scenario.

"We're disappointed (with the suspension). We felt we had the moral high ground, really," Lyon said.
"Clearly, we've asked the AFL to look into it. There's some grey areas with third-up in ruck contests.
"If you're a ruckman, you'd be concerned about third up because it's your ribs, it's your back (that's at risk) and, clearly now, it's going to get harder to protect yourself.
"I think everyone is a little bit uncomfortable with it."
The absence of Sandilands for the round-one encounter against the Western Bulldogs has left Jon Griffin, Jack Hannath and Zac Clarke in a three-way battle to fill the lead ruck role.
