Adrian Wojnarowski ‏@WojYahooNBA Blake Griffin hurt his knee in a Team USA scrimmage Wednesday and is returning to LA to be examined by team doctors, sources tell Y! Sports. Adrian Wojnarowski ‏@WojYahooNBA USA Basketball has summoned Anthony Davis to report to Las Vegas for training camp immediately, sources tell Y! Sports. Jayq's original title was "BG injured his knee... oh please no..." Rather than put up a new post, I edited the title to reflect the reality: What we know is that Griffin injured his knee and is headed back to LA. That's it. Of course we all feel the "oh please no" part, but... let's wait and see what happens. 11:28 update from Sam Amick: "...source confirms Clippers F Blake Griffin suffered a left knee injury yesterday at Team USA camp. "Not good," the source said when asked how bad it is."
