The NBA's Last Two Minute report said Klay Thompson made contact with Kevin Huerter's arm, which affected his jump, as time expired in the Golden State Warriors 116-113 win against the Sacramento Kings.
Huerter received the ball with 1.3 seconds left in the game. Huerter tried to shoot a 34 footer over Thompson, who appeared to hit Huerter on the arm.
Huerter could have sent the game to overtime if he had made that shot.
"The NBA knows it's a foul, and basically all they'll tell us is they missed the call, but you still lost," Brown said.
Stephen Curry traveled with 16.1 seconds remaining in the game, which was confirmed by the Last TwoMinute report.
The Kings have lost two games in a row because of missed calls.
Tyler Herro's game-winning bucket came after a missed travel call, according to the Last Two Minute report.
It's difficult being a King. Kevin received a foul. Somebody needs to make the right call at the end of the game. A man shoots a 3 and gets hit on the arm. A man takes six steps or three steps.
