19.1.3. If the injury is not the result of contact with an opponent, the player may
choose to be substituted, or may choose to charge their own team with a Time-
What does “charge” mean here precisely? That the player’s team effectively loses a time-out because of this injury call?
Presumably the overall outcome is that if a player calls injury without contacting another player, they must either a) leave the field, or b) their team loses a time-out. Furthermore, I presume that if they choose b) and do not have any time-outs left, the stall is increased by two. If the stall is already higher than 7, what happens? For instance, a player pivots and twists an ankle.
