I've taken this picture at a judo tournament using a Canon 50D with a Canon 24-70 f/2.8 (mark I). I had to shoot at ISO 3200 because of the bad light. This adds a lot of noise to the picture.
What f-stop did you use? In my humble opinion, you've got way too much depth of field there, which makes me think you did not photographed this at 70mm f/2.8 ...
