Chris Johnson's 10-day contract with the Memphis Grizzlies expires on Friday.

The Grizzlies can sign him to a second 10-day contract or for the remainder of the season.

"I root for these between-the-crack guys," general manager Chris Wallace said. "He's a confident guy without being overbearing about it. He's been a seamless fit. Hopefully, he can keep it up."

Wallace and vice president of basketball operations John Hollinger were impressed by Johnson last month at the D-League showcase. Wallace subsequently saw Johnson again during a D-League trip to Reno where the intention was to watch Tony Wroten.

"I figured why not go to the D-League and play for a chance to get a call-up?" said Johnson, a four-year college player at Dayton. "Once you sign that contract overseas, you're over there for a year. In the D-League, NBA scouts come check you out and look to potentially call you up. I'm grateful that the Griz did and just threw me out there. I'm trying to make the best of this opportunity."

Royce White and the Houston Rockets are closing in on a deal that would allow the rookie forward to return to the franchise and report to the Rio Grande Valley Rapids of the D-League.

The Rockets are close to making an announcement in which White would return to the team under a written agreement that includes key elements of the protocols that White wanted to have as an addendum to his contract, according to a source.

“Everybody wants to make it seem like wild, wild west standoff between me and the Rockets," White said. "That’s not the case here. There has been an issue that’s been identified. Mental health is not descriptive enough in CBA (collective bargaining agreement) and UPC (uniform player contract.) It being so vague makes us make it up as we go. There’s no protocol. We need to rectify that to make sure the environment is safe. If we’re making it up as we go, … that’s probably not the safest thing.”

The Houston Rockets have reassigned Terrence Jones to the Rio Grande Valley Vipers, Houston’s NBA Development League affiliate. 

Jones (6-9, 252, Kentucky) re-joins the Vipers following three previous assignments when he played in nine games, all starts, and averaged 19.2 points and 11.0 rebounds.  He has appeared in 11 games for Houston this season, averaging 3.1 points and 1.6 rebounds. 

The Houston Rockets will call up Patrick Beverley from D-League affiliate Rio Grande Valley Vipers, according to a source.

The move had been planned but was expedited due to Jeremy Lin's ankle injury.

Terrel Harris will signed with the Rio Grandy Valley Vipers of the D-League.

The Vipers are the Houston Rockets' owned affiliate.

Harris was waived this week by the Miami Heat.

The Houston Rockets have assigned guard Patrick Beverley to the Rio Grande Valley Vipers, Houston’s NBA Development League affiliate.  

Originally drafted in the second round (49th overall) of the 2009 NBA Draft by the Los Angeles Lakers, and later traded to the Miami Heat, Beverley was signed by the Rockets earlier today.   

The Houston Rockets have signed James Anderson.

Anderson, who was selected by San Antonio with the 20th overall pick in the 2010 NBA Draft, re-signed with the Spurs on Nov. 21, 2012 and appeared in 10 games this season, averaging 3.4 points and 1.4 rebounds in 9.4 minutes per game. He recorded a season-high nine points and four rebounds on Nov. 29 at Miami. He was waived by the Spurs on Dec. 20.

Anderson appeared in two preseason games for the Vipers this year, scoring 32 points in 46 minutes.
