The Oklahoma City Thunder announced Tuesday that it has signed point guard Shaun Livingston, the former No. 4 overall pick in the 2004 NBA Draft, to a multiyear contract. Livingston, 23, was originally drafted by the Los Angeles Clippers out of Peoria (Ill.) Central High after accepting a scholarship offer to Duke but deciding to forego college for the NBA. A former McDonald’s All-American who once drew comparisons to Magic Johnson because of his size, versatility, ball-handling, passing skills and court vision, the 6-foot-7 Livingston is hoping to restore a once-promising career after sustaining a severe knee injury in 2007. In 149 career games, Livingston holds averages of 7.3 points, 4.7 assists and 3.1 rebounds. His career was derailed when he tore all the major ligaments in his left knee and dislocated his knee cap after landing awkwardly following a layup attempt. Livingston missed the final 26 games of the 2006-07 season and the entire 2007-08 season. Livingston attempted a comeback at the start of this season with Miami but played only four games for the Heat, averaging 2.3 points in 10.3 minutes. He was traded to Memphis in January but was waived the same day. Livingston has played with the Tulsa 66ers, the Thunder’s NBA D-League affiliate, since early March, averaging 9.5 points, 6.0 assists, 3.5 rebounds and 29.4 minutes in 11 games. The Thunder also announced Tuesday that it has recalled rookie forward D.J White from the 66ers. White played in four games over two stints with the 66ers, averaging 14.5 points, 7.5 rebounds and 1.0 assists in 30.8 minutes. Livingston will wear jersey No. 14.
