With a little under six minutes remaining in the second quarter and Houston leading 55-32, Curry jumped high in an attempt to block a shot by Trevor Ariza in the paint. Ariza pump-faked to avoid the defense, causing Curry's momentum to carry him over the top of Ariza. Curry's backside contacted Ariza's shoulders, sending the 2015 MVP head first to the hardwood. Curry tried to brace himself for contact, but he landed hard on his back and right arm.
Play stopped as a shaken-up Curry lay on the court for an extended period of time. Eventually, Curry was able to walk to the locker room under his own power.
ESPN reported shortly before halftime that Curry sustained a head contusion and that he was questionable to return in the second half. After undergoing a series of tests, Curry returned to the court with 5:58 remaining in the third quarter.
This has been a season of pristine health for Curry, who played 80 games. The two-time All-Star has appeared in all 14 of Golden State's playoff games, producing postseason averages of 29.9 points, 6.6 assists and 5 rebounds entering Monday.
Game 5, if necessary, will be played at Oracle Arena on Wednesday. Golden State holds a 3-0 series lead.
