Nikola Jokic’s brother appears to PUNCH a fan in the face after Nuggets’ comeback win over Lakers – as NBA launch investigation into shocking footage of fight in the stands

The NBA is investigating a clip showing one of the brothers of Denver Nuggets star Nikola Jokic fighting with fans in the stands during Monday’s playoff game against the Los Angeles Lakers.

Shocking images have emerged on social media of the two men arguing while Jokic’s wife Nataljia held their young daughter nearby.

Jokic’s older brother Strahinja appears to be the one who threw the punch, hitting the man he was arguing with in the face.

He can be seen wearing a ‘Jokic 15’ jersey and climbing over a row of chairs to get closer to the man he was feuding with. The video that is going viral on social media is captioned: “Jokic Brothers going wild.”

The NBA has confirmed it is investigating the footage, while the Nuggets have been contacted by DailyMail.Com for comment.

The shocking scenes threaten to tarnish an otherwise wonderful evening for the team.

The Nuggets came from behind to beat LeBron James and his men 101-99 on Monday night, with Jokic leading the charge with 27 points and career-high scores for his team – last year’s NBA champions. They have a 2-0 lead in the series.
