The AFLPA are "deeply concerned" with the outcome of Zak Butters' Tribunal hearing regarding umpire abuse, which resulted in the Port Adelaide star receiving a $1500 fine.
The Power have yet to confirm they will appeal the decision, but are set to take this matter further.
"We are deeply disappointed by last night's Tribunal outcome for Port Adelaide's Zak Butters," AFLPA CEO, James Gallagher said.
"A misunderstanding about what was said on field should have been resolved in the aftermath of the match, not referred to the Tribunal.
"The Tribunal determining not to accept all of the evidence consistent with Zak's version of events, including testimony of Zak's teammate Ollie Wines, nor have sufficient doubt when upholding a charge is deeply concerning.
"In the off-season, we made it clear to the AFL that we would closely monitor the Tribunal's decisions during 2026 given concerns raised by players in recent seasons. It is important that all participants in the game, but most importantly the players, have confidence in the disciplinary system to which they're subjected.
"We've offered our full support to Zak and Port Adelaide in exploring their options to appeal."
Butters said immediately following the verdict that he was "disappointed" with the outcome.
"I stand by knowing what I said and what I didn't say. Especially what I didn't say. I'd like to thank the club for their support."
Port Adelaide will appeal the Tribunal's verdict, with chairman David Koch saying it's "certain they will".
