It was a rough night all around for the Los Angeles Sparks ... not only did they lose to the Las Vegas Aces -- their mascot got wrecked by a performer doing some backflips!!
The moment went down during a break in the action at Crypto.com Arena. As Sparky was interacting with the crowd, one of the dancers was backflipping his way down the court when he made contact with the dog ... sending him down to the ground.
But he didn't let it keep him down long .
