Milne was booed each time he touched the ball against Carlton in round 16 after returning from a club-imposed leave of absence.
He will learn the full extent of the prosecution case on July 26.
Power coach Ken Hinkley insisted his players would stick to football on Saturday night and not sledge the Saints' forward about matters before the courts.
"We've got a respectful group, I reckon, and they'll let due process take care of whatever else has to happen for him – we're out there to play football," Hinkley said.
"Stephen Milne's a part of their team and we'll treat him as a footballer.
"We want to beat them in football."
The Power will hope to exploit the fast, indoor conditions of Etihad Stadium and have brought in a couple of speedy runners.
With Kane Cornes suspended, the Power dropped Tom Logan and hard-nut Matt Thomas for the lightning-fast Kane Mitchell and hard-running youngster Sam Colquhoun.
Justin Westhoff was the third inclusion.
Hinkley admitted the indoor venue played a larger role in selection than an outdoor stadium would have, citing the Power's experience of playing Essendon there in round 15.
"We considered the venue a little bit more, [we] wanted some genuine run into our side and we certainly made that decision having only been there two weeks ago," Hinkley said.
"The venue allows you to play a bit braver…you can certainly make a decision a little bit quicker because you don't feel the elements of outside."
On the flip side of that though, Hinkley admitted skill errors were much easier to punish at Etihad Stadium.
Saturday night will be Colquhoun's third AFL game after he made his debut in round seven against Richmond.
The 18-year-old has consistently appeared in Central District's best at SANFL level and Hinkley said he would offer the club great flexibility both on Saturday night and in years to come.
"He gives that flexibility ... we know he can run through the middle and we know he can play at half back and play on the small forwards," he said.
"He's an elite user and he's a really hard runner."
