With Luka Dončić sidelined, Austin Reaves was in the midst of having his best game of the season Sunday against the Pistons.

And he filled in for Dončić in more ways than one, exchanging words with a courtside fan amidst his explosive scoring performance. 

The Lakers star guard walked up to a male fan toward the end of the first half sitting on the baseline opposite of the Lakers’ bench, which was closest to the basket the Lakers opened the game shooting at.

Reaves bent over in the fan’s face and the two exchanged words during the stoppage of play while the Lakers were up 60-45 with just over eight seconds left in the second quarter.

It wasn’t clear why Reaves confronted the fan, or what was said during the exchange, before the game ended.

But clearly the fan said something the former Oklahoma product didn’t appreciate. 

The exchange may have lit fire under Reaves. 

Already having 19 points at halftime, he scored another 13 points in the third quarter to help the Lakers take a 88-81 lead going into the fourth.

His 32 points entering the final quarter was a season-high and his first 30-point game of the season.
