Blazers forward Scottie Pippen underwent arthroscopic knee surgery on his left knee and is expected to miss the next three weeks reports Anne M. Peterson of the Associated Press.

Pippen has missed the last four games with swelling in his knee, although it is unclear as to how Pippen injured it.

If Pippen returns in the scheduled 3 weeks, he will be back in time for the final five games of the regular season.
