Former Putnam City High School standout and Oklahoma signee Keith Clark is on the Tulsa 66ers training camp roster. Clark has turned professional after a short stay at OU over the 2006-2007 seasons. The 6-foot-8 forward was declared academically ineligible, then enrolled at Rose State Junior College in January 2008. He was The Oklahoman’s All-State Player of the Year for the 2005-2006 season after leading Putnam City to the Class 6A state championship. Clark was one of the nation’s top recruits coming out of high school. Also on the 66ers’ camp roster are former OU players Terrell Everett and Ryan Humphrey. Tulsa, a NBA Developmental League affiliate of the Thunder, opens camp Nov. 17.
