Doc Rivers didn’t enjoy himself Wednesday. Not only did his Celtics see their six-game win streak end in a 90-78 loss to the Hornets at TD Garden, he had to coach against his son with incredible mixed emotions. Austin Rivers had eight points in 22 minutes off the New Orleans bench.

“You know, it was strange,” Rivers said. “It was funny, the one time he did something, I was about to say something and I didn’t say it – I caught myself – I forgot he was on the other team. Other than that, it’s just a strange dynamic. I didn’t enjoy it, honestly. I know it’s neat for everyone else, but as a father, I don’t know if I enjoyed that.”

Did his eye keep drifting to Austin?

“No, you detach from it, but you do see him,” the coach acknowledged. “I mean, you see your son run by you down the floor. I mean, that’s just different. The one time he made the layup in front of our bench and run right by you, you know I’m used to like, ‘Keep going!” and instead I’m yelling at my guy for letting him get to the basket. So it’s just different. George Karl this summer, we were laughing, and he said, ‘It’s going to be strange’ and he said, ‘your guy’s going to play more.’ And he was right.”

When Rivers got knocked to the floor by Paul Pierce at the end of the third quarter, Rivers said he didn’t fear for his son at all. As a matter of fact, he didn’t even flinch.

“No, I don’t,” Rivers said. “That’s one thing my kids know with me; when you go to the floor I don’t flinch. ‘Get the hell up.’ They all laugh at that, because that’s how I’ve always been. I never flinch. My wife would run out there; I’m not going out there. I mean, get the hell up.”
