Talmud (Rodkinson Edition) — Book 3…
“ This is not the point of variance, because all agree, that one who breaks a bone in a paschal lamb which was still raw incurs the penalty, as the lamb may be roasted and then be eaten. They do differ, however, concerning a man who breaks the tail of the lamb, which must not be eaten, but offered up on the altar. Those who hold that the sacrifice is a valid one hold him to the penalty, while the others claim that, as the tail must not be eaten, the man is exempt. ”
