James Harden suffered a strained left hamstring in Houston's double-overtime win against the Lakers.
Harden came up limping and dragging his left leg gingerly after he missed on a drive to the basket with 54 seconds left in the fourth quarter.
"Hopefully it is not that serious, just a pull on the hammy," an optimistic Harden said afterward. "Just got some treatment right now and hopefully, day to day, it gets better.
"But I'll be good," Harden added. "[It was concerning] especially [when] you don't know what it is or you have never experienced it before. Like I really can't run. If I am going to play. But I really couldn't run so let me go back here and see what is going on. We'll see. I think we don't play again until [Wednesday against Orlando]. ... So I got a couple of days."
