Upset about a lack of playing time, the 37-year-old Miller argued with his coach during a game Jan. 1. Miller's suspension was quickly rescinded, though he has not rejoined his team.
"At this point he's dealing with what he needs to deal with," Shaw said. "I'm focused on the team and what's best for the team right now. As I've said, I'm willing to coach any and everybody who wants to put the team first."
Miller was averaging a career low in minutes and was upset after being benched during Denver's loss to the Philadelphia 76ers.
"It's unfortunate what happened with us," Shaw said. "It's tough when you get toward the end of your career and things don't go the way they always have or the way you'd like them to. But right now everybody else on the outside has blown it up and made it a bigger deal than what it really is. Right now it's pretty much between him and our front office and his agent to deal with what happens next. I'm just here dealing with our guys and our next opponent."
After starting 37 straight games to start the year, swingman Gordon Hayward missed his second in a row Monday with a hip flexor injury. Still, no timeline for his return has been announced.
"He's getting better every day," Jazz coach Ty Corbin said. "He's a little better today than he was yesterday. We'll just see."
