The Grizzlies have signed Chris Johnson of the D-League's Rio Grande Valley Vipers to a 10-day contract, presumably to fill one of the roster spots opened up by yesterday's trade of Marreese Speights, Wayne Ellington, and Josh Selby to the Cleveland Cavaliers.

From the press release:

Johnson (6-6, 201) joins the Grizzlies after averaging 12.6 points, 4.0 rebounds and 1.81 steals on .439 shooting (.419 3FG shooting) in 29.0 minutes in 21 games (nine starts) for Rio Grande Valley this season.

The 22-year-old ranks fourth in the D-League in three-pointers made (54) and is tied for sixth in steals (38). Among qualifying D-League players, he places sixth in three-point field goal percentage, 12th in steals per game and tied for fourth in steal-to-turnover ratio (1.58).

Johnson joins Jon Leuer as a newcomer on the Grizzlies' bench. The Grizzlies are now at 12 players on the roster and will have two weeks or so to sign a league-minimum 13th player.
