The Sacramento Kings clinched their first 30-win season in eight years on Wednesday, but in continuing what has been a strange season for the team, the final seconds of the victory were clouded in controversy and tarnished by technical fouls.
For Cousins, it was his 16th technical foul of the season and will automatically earn him a one-game suspension.
The sarcastic claps occurred after the Kings were called for a five-second violation with 6.7 seconds remaining in the game and the Kings up by 14 points. Rondo, who was called for the violation, drew a double technical at the same time and was ejected.
"They said it was a violation and we clapped," Cousins said in a postgame courtside TV interview. "I guess they didn't like that."
Later, in the Kings locker room, Cousins said, "It's kind of unfortunate that it happened. I really don't know what to say about it. If I say something I'll get punished, and if I don't say something I'll get punished. I really don't know what the answer is anymore. I'm highly disappointed in what just happened."
If Cousins' technical foul is upheld, the Kings would be without him for Friday night's home game against the Miami Heat.
