The team announced the decision Friday, one day after the Wildcats improved to 5-0 by beating South Dakota State. Doutrive played 19 minutes in the game, scoring two points and grabbing four rebounds.
The 6-foot-5 Doutrive was suspended for the first two games of the season, also because of a violation of team rules.
The former five-star recruit played in three games this season as a sophomore and averaged 6.3 points.
He played in 26 of 32 games last year as a freshman, averaging 3.3 points and 3.0 rebounds per game.
