The Warriors trailed the Spurs 64-46 at the half on Tuesday night.
Draymond Green's breakaway dunk with 8:58 remaining in the third quarter pulled the Warriors to within 10 points.
But after yelling in the direction of LaMarcus Aldridge, Draymond was assessed a technical foul.
"Next time I dunk, I'm gonna yell again," Draymond declared after the loss. "I mean, it's kind of universal. I'm gonna continue to be me, and whatever happens, happens."
Kawhi Leonard made the ensuing free throw and the Spurs went on a subsequent 15-6 run to take a 20-point lead.
Draymond racked up 13 technical fouls last regular season -- the third most in the NBA.
Per NBA rules, a player receives a one-game suspension on his 16th technical.
Green was suspended for Game 5 of last year's NBA Finals after picking up his fourth flagrant foul point of the playoffs.
This offseason, Steve Kerr talked about Draymond keeping his edge without crossing over the line.
"It's not really a focus of mine not being me," Draymond added. "I know how to be me way better than I know how to be anyone else. So I'll just continue to try and work on being me, which really don't take much work."
