3.2. ART. 3 . . . A period must be extended by an untimed down if during the last timed down of the period, one of the following occured:
a. There was a foul by either team and the penalty is accepted, except for
those fouls listed in 3-3-4b.

ART. 4 . . . A period shall not be extended by an untimed down if during the
last timed down of the period, one of the following occurs:
a. When the defense fouls during a successful try/field goal and the offended
team accepts the results of the play with enforcement of the penalty from
the succeeding spot.
b. There was a foul by either team and the penalty is accepted for:
1. unsportsmanlike fouls,
2. non-player fouls,
3. fouls that specify a loss of down, or
4. fouls that are enforced on the subsequent kickoff as in Rule 8-2-2.
NOTE: The score is cancelled in the event of an accepted foul that specifies a loss of down.

Actually the illegal substitution foul we looked at was 3-7-6 "During a down, a replaced player or substitute who enters the field, but does not participate, constitutes illegal substitution." In the penalty section for this rule it indicates this is considered a non-player foul. We couldn't find an IP rule that fit since the players did not participate. So that left us with USC or IS non-player both of which fall under the rule you state above to NOT extend the period. What I would like to know is an official word on what rule applies when this happens.
