PORTLAND, Ore. -- The Portland Trail Blazers say center

Marcus Camby will need arthroscopic surgery on his left knee.

Camby hurt his knee in Portland's victory Monday night over the

Minnesota Timberwolves. The team says an MRI exam was initially clear,

but closer examination revealed a partial meniscus tear.

There is no timetable for Camby's return. His surgery has not

yet been scheduled.
