Giannis Antetokounmpo was left out of the Milwaukee Bucks team to face the Sacramento Kings on Monday following the birth of his son.
The reigning NBA MVP announced the arrival of Liam Charles Antetokounmpo in a post on Twitter.
It meant the Bucks, who go into the meeting with the Kings top of the Eastern Conference with a 45-7 record, will be without their star forward for just the fifth time this season.
Milwaukee have won their past four games and face the Indiana Pacers on Wednesday in their final outing before the All-Star break.
Antetokounmpo will captain Team Giannis against a roster selected by LeBron James in the All-Star Game this weekend.
