Despite a wealth of talent, Brandon Roy’s body continues to let him down.

After a pair of arthroscopic surgeries on his chronically-damaged knees last January, Roy returned to the court as a shell of the talented scorer who helped rivatalize the Portland Trail Blazers’ franchise.

And despite a brief cameo off the bench during Portland’s first-round playoff loss to the Mavericks, it sounds like Roy’s knees have failed him for good.

ESPN’s Chris Broussard and Yahoo’s Adrian Wojnarowski both tweeted Friday that the 27-year-old former Rookie of the Year will take a medical retirement.

Roy averaged a career-high 22.6 points with 5.1 assists and 4.7 rebounds per game during the 2008-09 season, and was selected to his third All-Star game the following season. After a meniscus tear in his right knee forced him back under the knife that April, he made a miraculous comeback only eight days later to help the Blazers to a Game 4 win in the first round of the playoffs.

Limited to only 47 games last season, Roy finished with season lows in points (12.2), rebounds (2.6) and assists (2.7) and expressed his frustration about a diminished reserve role during the playoffs.

The Blazers owe Roy $64 million over the next four seasons, but according to SB Nation, a medical retirement would allow the team to remove Roy’s contract from their books before next season.

Roy was one of the league’s bright young stars, and word of his impending retirement came as a shock only days after Portland coach Nate McMillan suggested he could start for the team this season.

Please say it ain’t so. Brandon Roy retiring. Losing one of the best 2 guards in the league before he’s ready to go. So unfortunate man! SMHFri Dec 09 16:25:33 via UberSocial for BlackBerryLeBron James
