Nets point guard Kyrie Irving exited the team's preseason matchup with the Lakers after aggravating his facial fracture on Thursday.
Irving suffered a left side facial fracture during a pickup game in September. He wore a mask against Los Angeles in Shanghai on Thursday, but he quickly exited the game after getting bumped by Lakers point guard Rajon Rondo.
The former Cavs and Celtics point guard was ruled out for the rest of the game, according to ESPN's Rachel Nichols.
Irving signed a four-year, $141 million deal with the Nets on June 30, signing with Brooklyn alongside Kevin Durant. The Duke product spent the last two seasons in Boston after six years in Cleveland. He won the 2016 Finals with the Cavaliers, and reached four All-Star Games in Cleveland.
The Nets host Minnesota in their season opener on Oct. 23. Irving's status for the matchup is unclear.
