PORTLAND, Ore. (AP) _ The Portland Trail Blazers placed forwards Shareef Abdur-Rahim and Darius Miles on the injured list Friday and activated rookie center Ha Seung Jin.

Abdur-Rahim, who has missed seven games with loose particles in his right elbow, will have surgery that could sideline him for five weeks.

Miles injured his left knee in the Blazers' 102-98 loss to the Los Angeles Clippers on Wednesday. He is expected to be sidelined for up to two weeks.

The Blazers planned to start Ruben Patterson at small forward on Friday night against the Miami Heat.

Abdur-Rahim had seen two doctors about the elbow problem and had planned to get a third opinion, but decided Friday to go ahead with surgery.

``It's been bothering me for a month,'' he said. ``It wasn't going to do any good to continue on with it. My thing is get it dealt with.''

Ha, a 7-foot-3, 305-pound South Korean, was a second-round pick, 46th overall, in last year's NBA draft. The Blazers signed him on Dec. 26 and placed him on the injured list with lower back pain a day later.

Abdur-Rahim is averaging 15.7 points and eight rebounds in 23 games. An eight-year veteran, he had never before missed more than one game in a row. Miles, his backup, averages 12.6 points and 5.1 rebounds.

Abdur-Rahim said he decided to have surgery instead of attempting to play through the pain until Miles got healthy.

``I don't feel good about it,'' he said. ``But a lot of things happen that you can't control.''
