Washington Redskins running back Clinton Portis bruised or sprained his right knee against the New York Giants on Sept. 23, and did not have a flare up of the tendinitis that sidelined him for the preseason. "In the first quarter of the game, he fell on his knee and bruised the inside of his knee, and that's what we're treating," director of sports medicine Bubba Tyer said. "He's got a contusion-slash-sprain that if you have to classify it would be a Grade I. We're taking it day to day, and our hope is that he'll be ready to play on Sunday."
