Landry returned to the Kings—where he spent parts of the 2009-10 and 2010-11 seasons—as a free agent in July, signing a four-year, $26 million deal, then missed much of the beginning of the season with a hip injury.
Landry, 30, played in just 18 games, averaging career lows of 4.2 points, 3.2 rebounds and 12.9 minutes per game.
He was a second-round pick of the Seattle SuperSonics out of Purdue in 2007 and was traded to the Rockets on his draft night.
He came to Sacramento at the trade deadline in 2010 as part of a three-team trade with Houston and the Knicks, with Landry and Joey Dorsey coming to the Kings from the Rockets and Larry Hughes coming to Sacramento from New York, with the Kings shipping Kevin Martin and Hilton Armstrong to Houston and Sergio Rodriguez to the Knicks.
The Kings traded him to New Orleans at the deadline in 2011 for Marcus Thornton.
The seven-year veteran has career averages of 11.5 points and 5.2 rebounds per game.
In five games with Sacramento, Johnson is averaging 1.8 points in nine minutes per game, shooting just 18.8 percent from the floor. He was originally drafted by the Kings with the 36th overall pick in 2012 out of UC Santa Barbara and was traded to the Pacers in a cash deal on draft night. He was waived by Indiana at the trade deadline to clear a roster spot after the Pacers traded Danny Granger to Philadelphia for Evan Turner and Lavoy Allen.
