Amy Duncan, the power forward's wife since 2001, apparently filed for a divorce in March, according to documents obtained by the San Antonio Express-News.
According to the paper, the Spurs star recently asked the court to delay the proceedings given that San Antonio is still in the playoffs.
Duncan didn't address reporters after Saturday's shootaround, and the Spurs' spokesman said he wouldn't be discussing personal matters.
The Spurs head into Saturday night's matchup against the Grizzlies with a 2-0 series lead.
