Dennis Schroder has left the NBA's campus in Orlando to be with his wife for the birth of their second child.
"Dennis is away from the team right now with his family," Donovan said.
Schroder is averaging 18.9 points, 3.7 rebounds and 4.0 assists this season as one of the NBA's leading Sixth Man of the Year candidates.
"It happened this morning so he's with his family at this point and time," Donovan said. "I'll have a chance to probably talk to him and find out a little bit more, if it's not later today, tomorrow. But right now for at least this game, he'll be out. We'll probably be able to gather some more information once we get a chance to spend a little bit more time with him over the phone."
