Jokic brothers have had multiple dust-ups

This is not the first off-court altercation that has involved the Jokic siblings. When Nikola Jokic was involved in a dust-up with the Phoenix Suns' Devin Booker during the 2021 Western Conference semifinals, Strahinja Jokic and Nemanja Jokic were visibly upset in the stands and had to be held back from the court.

In November 2021, after Nikola Jokic and Miami’s Markieff Morris were involved in an on-court scuffle that resulted in a one-game suspension for the youngest Jokic brother, Strahinja Jokic and Nemanja Jokic took the beef to Twitter.

In response to a tweet from Marcus Morris, brother of Markieff Morris – “Waited till bro turned his back smh. NOTED.”– the Jokic brothers opened the twitter account @JokicBrothers and responded: “You should leave this the way it is instead of publicly threatening our brother! Your brother made a dirty play first. If you want to make a step further be sure we will be waiting for you!! Jokic Brothers.”
