Jusuf Nurkic was in no mood. The Portland Trail Blazers center went right at an Indiana Pacers fan for heckling him earlier in the game.

Check out the Bosnian Blazers big man walk straight up to a courtside fan and chuck his phone:

While it's unclear what exactly triggered Jusuf Nurkic to react that way, one man claiming to be a security guard during the Blazers-Pacers game gave his interpretation of what happened.

“I'm the security guard. The fan was just talking to him in the fourth quarter, told Nurkic he was trash a few times from across the court and that was it. He came and did this right after the game!” said the man.

Of course, it's hard to verify if any of this is true. It's also possible that even if he was the security guard, he might have missed some of the slander that the man was dishing at the Blazers star.

But at the same time, Jusuf Nurkic could have definitely handled the situation with more poise. It's no secret that fans may cross the line with their trash talk at times, but the Blazers center could have very easily just walked away from the situation rather than go towards it.
