Minnesota Timberwolves guard Brandon Roy's career is in jeopardy again after he suffered another setback to his surgically repaired knees, league sources told Yahoo! Sports.
Roy, 28, has considered the possibility of retirement for the second time in three years, sources said, but no final decision has been reached. Doctors continue to have questions about whether his knees can withstand the grind of playing in the NBA.
Roy had surgery on his right knee on Nov. 19 and left the team again for further tests after returning to practice on Thursday.
Roy developed into one of the NBA's best shooting guards in five-plus seasons with the Portland Trail Blazers, earning three All-Star appearances and winning the 2007 Rookie of the Year award.
Several knee surgeries and the erosion of knee cartilage eventually forced his retirement in 2011. The Blazers used the NBA"s amnesty clause on Roy and paid him the remaining $63 million of his contract owed him.
After undergoing the platelet-rich plasma procedure that revived the careers of Kobe Bryant and Tracy McGrady, Roy embarked on a comeback over the summer. He signed a two-year, $10 million contract with the T'wolves, but played only five regular-season games before issues with his right knee again required surgery.
