Doc Rivers has admitted he is "a little concerned" that Jamal Crawford was forced to leave the Los Angeles Clippers' win over the Houston Rockets with a calf injury.

The guard left the game just before half time and was unable to return for the second half of the 101-93 victory with a strain.

The coach told ESPN: "Personally I'm a little concerned because no one was around him. When guys get injured when nobody's around them, that always scares me. We'll know more tomorrow. He said he felt better. I think he'll be OK, but I've been around the league awhile, so that's my concern."

Crawford has averaged 19 points per game this season.
