QB Matt Hasselbeck injured his right knee when hit low after throwing a pass. This did not look good. He needed help coming off the field. He pounded his hand on the ground as if he knew this could be serious. We will advise. UPDATE: He is putting on his shoe and bending his knee. Appears as though he intends to come back in the game. At the very least, he is testing the knee. SECOND UPDATE: They are saying sprained knee, return is doubtful, he just left the stadium, walking through the tunnel.
