Elsewhere in the report, it was concluded that Jazz striker Joe Ingles fooled Lillard to stay 1:13 on a 3-point attempt that Lillard made, bringing the match to 112, but no calls were made.
Crew chief Josh Tiven admitted that officials missed the goaltend.
The clock resumed when the Jazz got the ball after Swanigan's shot.
"There ain't no way to take the sting out of it", Lillard told ESPN.
Apart from that monumental no-call, the competition also determined that Royce O'Neale did not make Lillard a mistake during his ride to the basket (it was determined as a correct no-call).
The moment at the end of the game overshadowed what was another sublime performance from the Portland point guard who went off with 42 points, six rebounds and six assists.
Damian Lillard is incredibly upset after a missed goalkeeper call as 9 seconds remain in the game. "All night, they're double-teaming me, trapping me, trying to be physical, I shot three free throws the whole game". I'm telling them they are grabbing and holding the whole game - that's fine.
"It cost us the game, man", he said. We're in the playoff race and they cost us the game on an easy call.
Fans are pushing for the star not to be fined for the outburst but it has once again shone an unflattering light on the National Basketball Association referees.
"It cost us the crap game, man", said Lillard, who felt the officials were lenient with Utah at all times. Still, Lillard and his teammates were apoplectic about the situation.
He ripped them when talking with the media after the game, saying the refs cost the Blazers the game. It's a loss on our record and we're in a playoff race and we need every game that we can get.
"Since then we have analyzed it, through the post-game video review, and unfortunately we saw that we missed the play and should have called a goal violation". "Not just bad, terrible".
