Irving stepped away from the team because of personal reasons on Jan. 7 and will be missing his seventh consecutive game.
Prior to the game, Nash told reporters he expects Irving to practice on Tuesday ahead of a game against the Cleveland Cavaliers on Wednesday.
Nash told reporters on Jan. 7 that he did not know why the guard was away, and Joe Vardon of The Athletic reported that night that Irving didn't know when he would return.
The 28-year-old has been a difference-maker when on the court, averaging 27.1 points, 6.1 assists and 5.3 rebounds per game this season. He averaged a career-high 27.4 points last season in his first year with the Nets.
A shoulder injury limited Irving to only 20 games last year. It was the third straight year in which he missed at least 15 regular-season games.
The Nets have proved they can remain competitive without Irving, but they'll need him to reach their lofty expectations this season.
