West made the trip to Miami but sat out against the Heat because of an "internal matter," Brown said. That was the same reason given for West missing Wednesday's win at Orlando.
West was indicted Nov. 3 on additional weapons and traffic charges stemming from his Sept. 17 arrest for speeding on a motorcycle and carrying multiple weapons. He has been treated in the past for bipolar disorder, and his wife recently filed a domestic violence report against him.
Brown said West's inactive status didn't create a major problem regarding the rotation.
"In my mind I have a way I'm going to go if he's active, and if he doesn't go, I have a slightly different way," Brown said. "I'm good either way. You're talking about a guy that started for us last year and is going to play minutes if he is available. If he's not, somebody else has to step up."
West has scored 22 points in four games this season, all as a reserve. He hasn't played since Friday.
He started last season for the Cavs and averaged 11.7 points per game, then averaged 13.8 in the playoffs.
