Jaylen Brown and Nike's long-standing feud took a wild turn after the recent handshake incident involving Brown and Giannis Antetokounmpo.

One of the surprising storylines in this early NBA season is a budding feud between Boston Celtics superstar Jaylen Brown and two-time MVP Giannis Antetokounmpo. The pair clashed during the Celtics' win over the Milwaukee Bucks on Sunday, which culminated in Brown calling Antetokounmpo a "child" during his postgame press conference.

Jaylen Brown and Nike’s feud lives on. The Celtics star fired back after the sportswear brand appeared to take a shot at him while celebrating Bucks star Giannis Antetokounmpo’s 59-point performance in a win against the Pistons on Wednesday.
