Lots of people die in Discworld and death doesn't appear in the text, but as he is everywhere at the same time, it's reasonable to assume he is there. Look at how many people died in Jingo, or Interesting Times.
Actually, I want to drop Ponder Stibbons, move Vimes to left back, bring in Dorfl (good call WannabeAngua) to partner Detritus in the middle of the defence and have Death as the trainer who runs on with the magic sponge (or scythe - depending on the seriousness of the injury) and who provides the players with those bikkies with the chocky bits in at half time, or mint cracknels (or is that a different thread?).
Teppic can be the sub.
