Minnesota Timberwolves guard Brandon Roy in working on strengthening his knee and went through a non-contact practice on Thursday. Roy underwent arthroscopic surgery on his right knee on Nov. 19 after playing in only five games this season.

"I've been doing some cardio, working on strengthening my right knee. Next week I hope to go full bore," Roy said on Thursday. Roy added that he is confident that he will be able to return and that his knee feels better since undergoing surgery; there is no specific timetable for his return.

Roy retired after the 2010-11 season due to bone-on-bone pain in both of his knees. He decided to return to the league this year and signed with the Timberwolves on July 31, but suffered a set back after a collision in a preseason game on Oct. 26. In his five games this season, Roy is averaging 5.8 points and 4.6 assists in 24.4 minutes per game.
