Injured Player out for one "Down"

[jchamp]

To "repeat/replay a down" is a colloquialism that is not defined in the book. The correct term is the number of the down, or a series of four numbered downs. The number of the down is what is important. Rule 5-2-2 describes that the NUMBER of the down is the same as the preceeding down when certain fouls occur during that down. It does not say that the down is "replayed", "repeated" or any other language that nullifies the fact that the down did, in fact occur. Since rule 9-6-4 says nothing about a player staying out of the game for one number of a down, then as soon as the ball becomes legally live, and legally dead, the requirement for 9-6-4 is met and the injured player may return.
