The Celtics overcame an 18-point deficit to stretch their incredible unbeaten record to 11 games after beating the Hornets 90-87.
Their record looked like it would come under serious threat when Aron Baynes incidentally smacked Irving in the face with a trailing arm.
The former Cleveland Cavaliers guard immediately collapsed to the floor and left the game due to concussion protocols.
Boston were already without Al Horford for the game while their other All-Star in Gordon Hayward is out for the season.
But the Celtics’ second unit got the job done with Shane Larkin coming up with 16 points in just 17 minutes including four-from-four three pointers.
After the game, attention quickly switched back to Irving’s welfare and whether Stevens knew of any update.
And while the Celtics’ head coach admitted he was yet to speak to him, he did reveal how Irving made sure to congratulate his team on their comeback win.
“I haven’t talked to him but he sent a text to a group of us right when we walked back into the coach’s office,” Stevens said.
“He said ‘way to go, great win’ so he obviously watched the rest of the game.
“He left at half-time so I have not talked to him yet.”
