Danny Manning, last year's No. 1 NBA draft pick, underwent reconstructive knee surgery Saturday and will be in rehabilitation for up to a year, the Los Angeles Clippers announced.

The surgery on Manning's right knee was performed by Dr. Stephen J. Lombardo, who said damage to the joint was limited to a torn anterior cruciate ligament."We're happy to learn that Dr. Lombardo found no further damage in Danny's knee," Clippers general manager Elgin Baylor said in the statement. "We know the rehabilitation plays a great part in the recovery of a patient.

"With Danny's work ethic, desire and determination we're very optimistic about his return."

A tendon from his Manning's right leg was removed and inserted into the knee to take the place of the damaged ligament, the team said in a prepared statement.

Manning, a 6-10 forward was named NCAA College Player of the Year and NCAA Tournament Most Valuable Player after lead the Kansas Jayhawks to the national title.

He injured his knee Jan. 5 in a game against Milwaukee as he attempted an uncontested layup.

Manning, 22, will remain at Centinela Hospital Medical Center in suburban Inglewood for 3-4 days and then will begin a rehabilitative program at the Kerlan-Jobe Orthopedic Clinic for the next 9-12 months.

Manning played on the 1988 U.S. Olympic basketball team before joining the Clippers, with whom he averaged 16.6 points, 6.6 rebounds and 3.1 assists in 26 games this season.

Manning is expected to begin workouts on a stationary bicycle in 3-4 weeks, start running in 3-4 months and begin light basketball workouts in six months.
