Neymar was left out after the 34-year-old missed a recent Santos FC match with muscle fatigue - a game Ancelotti had planned to watch in person as part of his assessment ahead of naming the squad.
Santos is now only two points above the relegation zone as a result of the loss.
Neymar returned to action two weeks ago, having been out since Brazil's CONMEBOL World Cup qualifier against Uruguay in October last year when he suffered the injury.
Neymar is available to play for Saudi Arabia club Al-Hilal in an AFC Champions League Elite match next week after one year on the sidelines due to injury.
Reports said that the suspects-two of whom were armed-were on the lookout of Bruna Biancardi and the couple's daughter Mavie.
Neymar will have a private plane for his use and will be staying at a 25-bedroom mansion during his Al Hilal stint.
"I am here in Saudi Arabia, I am Hilali," Neymar said in a video posted to Al Hilal's social media accounts.
Mbappe is mired in a contract standoff and was widely expected not to be in the squad after having been left out of the pre-season tour to Japan and South Korea. He trained apart from defending champion PSG's first-team regulars all week.
Soccer fans around the world took a greater interest in watching the French league last season when PSG boasted superstars Messi, Mbappe and Neymar in attack.
