If I remember rightly it was a night match. The vivid memory I have is the injured knee was noticeably larger than the other. One of my best memories of him playing was when we were playing West Ham. We were playing towards the scoreboard end, Bobby Moore was tight on his back, somebody played a ball up about chest height, just before the ball reached them Bell had read the flight of the ball and spun one way round Moore the ball went the other side of Moore, Bell was gone and one of the best players in the world at that time stood there with a bemused look on his face.
