Stephen Curry is not expected to miss an extended period of time as a result of the "scary" back injury sustained in the Golden State Warriors' win over the Houston Rockets, Steve Kerr has said.

The Warriors ran out 108-94 victors at Toyota Center on Wednesday despite losing their talisman to a freak injury on the final play of the third quarter.

After missing with an off-balance three-point attempt, Curry could not stem his momentum, collided with the risers at courtside and was unable to break his fall.

Curry, who suffered a tailbone contusion as a result of the incident, initially tried to get back up but went to the locker room for treatment and was ruled out for the rest of the game.

Head coach Kerr said he was unable to give an immediate timeframe for Curry's return, though he is confident it will not be a long absence.

"He says he's going to be fine long term," Kerr said. "It's going to bother him, though, for definitely the next few days. 

"I've no idea if he'll play in Memphis [on Friday], but he seems to be feeling like he'll be okay over the next week or so, but we'll see.

"And please don't take that to mean that I'm saying he's going to be out for a week. He could be practicing [Thursday] for all I know, but we'll give you an update as soon as we have one."

Kerr, who said Curry does not need an X-ray or additional tests, added: "I didn't see it at first, and then after the buzzer sounded, I saw everybody getting up to look at what was happening. 

"So, it was scary. He told me after that he started backpedalling and normally he would have basically fallen back into the fans sitting courtside, but there's nobody there, obviously. 

"So, he said he sort of took that step expecting to stop and he just kept going and fell right on his tailbone, on that piece of metal on the sidelines that holds the stands in place."

The Warriors are 21-20 as a result of the victory, which provided a riposte to the 128-97 blowout they suffered against the Los Angeles Lakers last time out.

Draymond Green says he and the rest of the roster have to step up if they are to be without Curry.

"Hopefully it's not too long but at the end of the day, the most important thing is his health," Green said. 

"When you're dealing with a tailbone injury, if that's not right, other things tend to shut down and you start to use other muscles that you shouldn't be using. 

"Next man up, but other guys got to continue to step up, including myself."
