Brandon Roy plans to retire because of degenerative knees, according to two sources.

Roy was evaluated this week by doctors.

“You can’t do this,” the doctor told Roy, according to one of the sources. “You might end up not walking.”

One of the sources described Roy as very “emotional” and said he needed “time to rest”.

In a surprise announcement on Monday, the Blazers said that they intended to not use their amnesty clause on Roy and that he would enter training camp as starting shooting guard.
