Nike’s jerseys are hanging by a thread to start the NBA season.

The apparel and shoe giants have opened an investigation into why its jerseys have ripped after the one belonging to their poster child, LeBron James, ripped right down his back during the Cavaliers’ opener against the Celtics on Tuesday night, according to ESPN.

The jersey was torn after Celtics guard Jaylen Brown grabbed at James’ jersey while guarding him during the Cavaliers’ 102-99 win.

Nike is puzzled with the sudden jersey malfunction since the company used a similar model during last year’s Summer Olympics in Brazil and during the college basketball season last year with no problems. This season is Nike’s first as the exclusive supplier for the league after it won the NBA’s jersey rights in an eight-year deal reportedly worth $1 billion, outbidding Adidas this year.

It’s the second time an NBA jersey has ripped in less than a month. Lakers guard Tyler Ennis’ jersey split between the numbers 1 and 0 during a preseason game against the Timberwolves.
