Head coach Brad Stevens previously said Irving, who completed the morning shootaround session, will be in the lineup to face the Nets "unless I hear otherwise," per Adam Himmelsbach of the Boston Globe.
Irving told reporters Tuesday his daughter accidentally hit him in the face over the weekend, and he jokingly said it was a struggle not to cry in front of her.
The four-time All-Star is off to a strong start with the Celtics after his offseason trade from the Cleveland Cavaliers. He's averaging 20.3 points, 5.2 assists, 3.1 rebounds and 1.9 steals across 13 appearances.
His expected return will send big man Aron Baynes to the bench as Boston returns to a smaller lineup. It will also reduce playing time for reserve guards Terry Rozier, who scored 16 points in 28 minutes against the Raptors in the team's 12th straight win, and Shane Larkin.
Irving should make a smooth transition back into action as the Nets will be without point guard D'Angelo Russell as he deals with a left knee contusion.
