LOS ANGELES -- Golden State Warriors star forward Jimmy Butler suffered what appeared to be a left forearm injury in the third quarter of Thursday night's 123-116 win over the Los Angeles Lakers and was uncertain about his status for Friday's game against the Denver Nuggets.

Butler said he might have to undergo further testing on his forearm and see how he feels on Friday to determine if he can play at Chase Center in the second game of a back-to-back. He was able to return and play the entire fourth quarter.

"Part of the game [is] getting nicked up a little bit," Butler said after also having three steals in 36 minutes. "I hope that I'm going to be all right though, so we'll see tomorrow."

Butler said he did not undergo an MRI or X-ray on his forearm after the game. Asked if he would need to do so, he said, "Maybe. Probably. I hope not."

Butler's return in the fourth quarter helped the Warriors close out their fourth consecutive win, as he scored seven of his 11 points in the final 12 minutes.

"Jimmy's tough as hell, and we needed him to come back in to close that game up," Golden State power forward Draymond Green said. "He came back and he was exactly who he's been and who we needed him to be."

Stephen Curry, who has been playing with a pelvic contusion that cost him two games recently, took a fall on his tailbone Thursday night but shook off the injury and finished with 37 points.

Curry said he should be fine and that the bigger issue is wearing a protective pad on his back, which he expects he'll have to do for the remainder of the Warriors' season.

When asked if he knows if he will play in the second of a back-to-back Friday, Curry said, "I'm not sure." Head coach Steve Kerr said he thinks Green and Curry will play against Denver.

The Warriors (45-31) are in fifth place in the Western Conference standings with six games remaining in the season.
