4:39pm: Roy is expected to miss a month after undergoing successful arthroscopic surgery today, according to the Timberwolves (Twitter link).
9:31am: The Timberwolves have officially confirmed (Twitter link) that Brandon Roy will undergo arthroscopic surgery on his right knee today, as Jason Quick of the Oregonian first reported last night. While the team will wait until after the procedure to set a timetable for Roy's recovery and return (Twitter link), Adrian Wojnarowski of Yahoo! Sports reports that the former Blazer is expected to be out for "a couple weeks" (Twitter link).
Roy's procedure is obviously bad news for a Minnesota team that's been ravaged by injuries early in the 2012/13 season, but the club did give itself some insurance when it negotiated Roy's contract. As we outlined in September, the second year of Roy's T-Wolves deal will become non-guaranteed if his knees keep him sidelined for a significant portion of this season.
The 28-year-old will have to play more than 1400 minutes or be active for 65 or more games to ensure that his contract is guaranteed for the 2013/14 season. Those criteria are still within reach, though this setback means it will be an uphill battle to achieve them.
