Curry was sprawled on the court after tripping when Jazz forward Marvin Williams inadvertently fell onto him, smashing the Warrior guard’s head into the hardwood.
Teammates and trainers surrounded Curry while he remained face first on the court for a couple of minutes before walking to the training room with a towel covering his head.
Curry didn’t return for the final 8:49 of the Warriors’ second win over Utah in three nights. Golden State’s medical staff called the injury a headache.
Guard Gordon Hayward scored 18 points with six rebounds and forward Marvin Williams added 16 points off the bench, but the Jazz (1-11) fell for the third consecutive game after picking up their only win last Wednesday.
Klay Thompson and Harrison Barnes each scored 17 points and power forward David Lee totaled 14 points and 14 rebounds as the Warriors (8-3) won their fourth straight game.
Curry didn’t score until early in the second quarter, but he then sparked the Warriors to a 28-point lead early in the second half.
Utah used a 14-0 run in the third quarter to make things interesting for a while, but Curry then all but put the game out of reach to begin the fourth quarter.
Curry hit a jumper, assisted on forward Draymond Green’s layup and then swished one of his four 3-pointers in a 7-0 Warrior run that put Golden State ahead 85-65.
NOTE: Warriors forward-center Jermaine O’Neal did not travel to Utah after being injured Saturday. He is day-to-day with a bruised right knee and a strained right groin. To take O’Neal’s roster spot, Golden State signed Dewayne Dedmon from the Santa Cruz Warriors.
