Golden State Warriors guard Stephen Curry has suffered a broken hand after falling awkwardly in his side's 121-110 home defeat by the Phoenix Suns.
The injury to the left hand of the two-time NBA most valuable player happened during the third quarter of the match.
X-rays confirmed the break but no time frame has been given on how long 31-year-old Curry might be out.
The defeat in San Francisco means the Warriors have won one and lost three of their opening four games of the season.
"It's obviously been a tough start for us on many levels and obviously this puts us in a tough spot," said head coach Steve Kerr who has guided the Warriors to the NBA Finals in each of the previous five seasons, winning three.
