The Portland Trail Blazers are filing a protest to challenge the result of a 111-109 loss to the Oklahoma City Thunder, reported Adrian Wojnarowski of ESPN.

The Blazers contend that Chauncey Billups called a timeout on the sideline before a referee whistled Malcolm Brogdon for a travel with 15.1 seconds left in the fourth quarter.

The Blazers led 109-108 at the time.

After angrily reacting, Billups was called for two technical fouls and ejected from the game.

"We've got timeouts. Referees usually are prepared for that, you know, that instance, that situation. I'm at half court, trying to call a timeout. It's just frustrating," said Billups after the game.

Crew chief Bill Kennedy stated that Billups was not granted a timeout because he was positioned behind a ref when calling a timeout.

"The referee in the slot position was refereeing the double team that was right in front of him, which makes it difficult for number one to hear and number two to see a coach request a timeout behind him," said Kennedy.

The NBA will have five days to make a decision once a protest is filed.
