The goalkeeper required 10 staples to close a cut in his face after being caught by Singo’s boot when the defender attempted to jump over the on-rushing Italy international while through on goal during Monaco’s 4-2 home defeat by PSG.
Singo, who had been booked earlier in the game, was not punished for the incident, which saw the keeper to have to leave the pitch.
Singo apologised to Donnarumma, saying: “My gesture was obviously not intentional but I was able to see afterwards that he had a significant injury to his face.”
The 23-year-old Ivory Coast international, who joined Monaco from Italian club Torino in 2023, was racially abused on social media after the match.
Monaco say the club “firmly condemns the unacceptable racist comments” and that “such behaviour has no place in sport, either on or off the pitch”.
The Ligue 1 club added they would be offering their “full support” to the defender.
Singo and Donnarumma spoke after the match, and the Italian was able to travel back to Paris with his team-mates.
PSG said Donnarumma would have “medical examinations” on Thursday and will “have to rest for several days”.
