Replaced Player

[EEE]

3-7-1 Between downs any number of eligible substitutes may replace players. Replaced players shall leave the field within three seconds.

2-32-12 A replaced player is one who has been notified by a substitute that he is to leave the field. A player is also replaced when the entering substitute becomes a player.

So A1 runs on the field into the huddle and never notifies A2 that he is being replaced. When do you call illegal substitution?

After 3 seconds. You just cited the rule.

The 2010 Points of Emphasis review of the 2010 Rule Changes suggests, "Upon recognition, the replaced player has 3 seconds to start to his/her bench area." It also clarifies the recommended time frame, " is not impacted or not by whether a team huddles".

The answer to your question is that 3 seconds (ish) after a substuitute enters a huddle, someone should start leaving.
