Steve Nash won't be back tonight

DALLAS -- Steve Nash won't return to tonight's game due to a stinger suffered when he and Mavericks center Tyson Chandler collided chasing a loose ball.

It appeared Nash's shoulder plowed into Chandler's right hip. A more accurate description of the injury is being pursued, but it is clear Nash won't be back. The collision occurred at the 7:17 mark of the first quarter. Chandler remained in the game.
