The Sixers have given multiyear contract extensions to senior vice president and assistant general manager Tony DiLeo and director of player personnel Courntey Witte, the team announced today.

Terms were not disclosed.

"During my time here, I've had a chance to see first-hand the work ethic, time and dedication both Tony and Courtney have invested in this organization," president and general manager Ed Stefanski said in a statement. "I am not only confident and comfortable that their experience and knowledge will continue to be invaluable assets, but I look forward to working with them as we collectively pursue our goal of bringing a championship to Philadelphia."

DiLeo is in his 19th season with the Sixers' basketball operations department. After spending four seasons as the Sixers director of player personal (1999-03), he was promoted to his current position in September 2003. He is primarily responsible for assisting Stefanski with player acquistions and also supervises the team's draft effort, and college and professional scouting systems.

Witte is in his 11th season with the basketball operations department and 22nd overall in the NBA. After serving as the Sixers director of scouting for two seasons (2001-03), Witte was promoted to his current position in September 2003. He will continue to be involved in all aspects of the team's basketball operations, including the draft night preparation and the coordination of Sixers professional scouting and collegiate player evaluation process.
