Substitution Infraction Situations

[reff4e]

Two situations involving substitution infractions (or not)....Federation rules:

Play 1:
Following a possession change during which team A offense has huddled at the sideline, A comes to the ball and attempts to line up with 13 players. Seeing the confusion, the coach immediately asks for a time out (he has 3 left). Is this an illegal substitution infraction? If so, how do you determine which replaced players failed to ‘leave immediately.’ Do you grant the time out, and still assess the substitution penalty, or do you ignore the substitution infraction since the coach called time out before ‘deception’ could occur?

Play 2:
During a time out for measurement, substitute A12 comes to the huddle on the field. Replaced player A11 stays at the huddle to observe the measurement. After the measurement, the referee signals the ball ready-for-play and A11 leaves. Is this an illegal substitution infraction?
