Miami, FL (Best E Casino) - The Miami Heat signed former Los Angeles Clippers guard Shaun Livingston on Friday to an undisclosed contract.

Livingston has not played since a gruesome knee injury sidelined him in February 2007. The 23-year-old underwent successful reconstructive left knee surgery but did not participate in the 2007-08 season.

The Peoria, Illinois native, who decided against attending college after his draft stock rose due to a prolific high school career, tore the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament and lateral meniscus when landing awkwardly on a drive to the basket in a game against Charlotte. The 6-foot-7 combo guard also suffered a patella dislocation, in addition to a previously diagnosed tibia/femoral dislocation.

Livingston, the fourth overall selection in the 2004 NBA Draft of the Clippers, averaged 7.4 points and 4.8 assists in 145 games -- 60 starts -- in three seasons with LA.

The Heat also requested waivers on guard Tre Kelley on Friday.
