The Boston Celtics have signed Chris Johnson to a 10-day contract.

Johnson is averaging 19.4 points and 6.8 rebounds in 20 games this season with the Rio Grande Valley Vipers of the D-League.

“Chris has been playing very well. We need a wing player, we need someone who can shoot the ball, so Chris will add some depth to our team for now,” president of basketball operations Danny Ainge said to the Boston Globe before practice Thursday.
