The Bulls will be listed as questionable for Game 5 on Wednesday due to the health and safety protocols that LaVine has entered.
LaVine will not travel with the team to Milwaukee later in the day because he is not feeling well. The Bulls will know more about LaVine's status for Game 5 after he goes through more testing.
In four playoff games, LaVine is averaging 19.3 points against the Milwaukee Bucks.
This will be the third time that LaVine has entered the league's protocols, following a stint in December and the end of the 2020-21 season.
Game 5 is in Milwaukee.
