Andrew Bynum of the Los Angeles Lakers is no longer the only one suffering from a knee injury out of both playoff teams. During last night's game 6 of the playoffs between the Lakers and Celtics, Boston's center, Kendrick Perkins, had to leave the game after just five minutes into the first quarter. It has since come out that he now suffers from a sprained knee. We must hope that he waits long enough for his full recovery before starting to play again and that he does not experience chronic pain for the rest of his career.
