During warm-ups prior to their game against the Boston Celtics, Oklahoma City Thunder guard Russell Westbrook suddenly ran off the court without a hint of a warning. Did he just see a ghost?

In a video posted via Streamable, Westbrook is seen warming up, but then suddenly stops to look towards the stands before running off the court.

Below is the video:

It is unclear what Westbrook actually saw. Maybe he saw a real ghost or it's part of his antics to get a laugh out of the spectators. Regardless, Westbrook continues to amaze NBA fans on and off the court.

The Thunder would lose that game after a three-pointer by Marcus Morris of the Celtics with 1.2 seconds remaining. It gave Celtics the 100-99 lead which was eventually the final score of the contest.

The Thunder could've won the game on the previous possession had Carmelo Anthony not miss his two free throws later in the contest. As reported by Royce Young of ESPN, Melo took responsibility for his team's loss:

“Usually, this game would have been iced,” Anthony said. “Making those free throws, walking out of here with a big road victory, especially here in Boston, where it's always tough to win a game. It's easy to beat yourself up about it, but it happens. I'm pretty sure I'll beat myself up about it tonight. And tomorrow is a new day. You don't even need to kind of harp on it or let it linger. It happened. I had an opportunity to make two free throws. I missed them. I'm pretty sure I'll get that opportunity again.”
