The Kings are in talks to trade foward Luc Mbah a Moute to the Minnesota Timberwolves for forward Derrick Williams according to league sources.
The players would have to pass physicals to complete the deal, which could happen as soon as Tuesday.
The Kings acquired Mbah a Moute from Milwaukee in July for two second round draft picks.
Williams was the second overall pick in the 2011 NBA Draft out of Arizona. Williams, however, has not had an impact with the Timberwolves.
There are questions about what position Williams should play. The Kings need a small forward, but Williams is viewed as a tweener by many whose best position might be power forward.
The Kings already have Jason Thompson, Patrick Patterson playing power forward.
John Salmons and Travis Outlaw have played small forward, with Outlaw also spending time at power forward.
Mbah a Moute was brought in to be the defensive stopper the Kings have lacked in recent years.
After sitting out most of the preseason with a sore right knee, Mbah a Moute eventually cracked the starting lineup and had been the Kings' most versatile and best individual defender.
Williams (6-8, 240) is averaging 4.9 points and 2.4 rebounds in 11 games this season. Williams is playing just 14.7 minutes per game.
Williams averages 10.1 points and 4.9 rebounds for his career.
Mbah a Moute is averaging 4.4 points and three rebounds in nine games with the Kings.
