Brandon Roy is set to announce his retirement from basketball because of the degenerative knee condition that has left him with no cartlidge. Roy only appeared in 47 games for the Blazers last season because of the injury and has been advised by doctors that he could risk not walking in the future if he continues to play.

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

The former All-Star guard has undergone six operations on the knees, the most recent being arthroscopic surgery in January from which he was able to return for the Blazers short playoff run. Amid rumors that Portland were going to use the amnesty clause to waive the one-time face of their franchise, management had stated that was not the case, but Roy felt it was better to retire than endure the process of being waived and then claimed by another team.

Roy will retire having played five seasons with Portland, he was the Rookie of the Year in 2006-07, and has career numbers of 19.0ppg, 4.3rpg and 4.7 apg. Brandon was also a three-time All-Star.
