But Suns coach Steven King has defended Miller, saying Zorko's accusation was disrespectful and any contact was accidental.
The pair's long-running rivalry hit new heights on Saturday, Zorko furious after Miller laid a diving tackle and one hand slipping towards the Lions veteran's groin.
Miller avoided any penalty for the incident, but did cop a $1500 fine for his part in a fourth-quarter scuffle as the Suns ran away with a 41-point win that ended Brisbane's nine-game winning streak against them.
Zorko had to be dragged away from that contest and was still fired up on Monday.
"It's interesting, you're allowed to grab the groin region now and squeeze it and do whatever you want to it," Zorko said on SENQ Breakfast.
"So that's an interesting rule that's been cleared by the AFL.
"It's quite interesting that (he) got off. We had really good evidence to support the case.
"I tell you what, my groin region is quite bruised at the moment. It's funny how that all happens."
To be found guilty of misconduct, the Lions would have to prove Miller's actions were intentional.
"It must have been an accident ... it's an accident when they get up and smile and laugh about it, isn't it," Zorko said.
King said on Monday night that Miller had asked for the role on Zorko and lauded him for how he executed it.
"I will defend Touk every day of the week. He's an amazing character, leader.
"I saw as just two ferocious competitors attacking the ball with real vigour, and Touk just making a great tackle. I know for a fact that was Touk's intent.
"We found those remarks a bit disrespectful.
"We know the integrity of the man and we'll back him 100 per cent."
Asked about any contact to Zorko's groin area, King said it was "completely accidental".
Miller and Zorko's running battle has been the captivation of the Queensland rivalry, Miller admitting the fashion of their drought-breaking victory was as satisfying as it was crucial to keeping their faint finals hopes alive.
"There was part relief, excitement and thrill we could put them to the sword," Miller said post-game.
"We kicked some goals late and had that bit of party time ... I was happy to be in the moment and relish that."
The loss was a missed opportunity for Brisbane to jump Port Adelaide, who were beaten later on Saturday by Adelaide, into second place.
The Lions could be without influential defender Keidean Coleman for this weekend's trip to face Fremantle, the club yet to provide an update after he suffered an eye injury from accidental contact against Gold Coast.
