Not for me.
Player can only return at stoppage in play - injury, scrum, lineout or after a score.
Therefore a player binned at 71 mins may as well head to the showers for an early one.
The OP posited a situation where 90+ seconds of continuous play followed after time expired, and then ended with a penalty. The 10 minute playing time for the bin has expired and the game has not ended.If a player is binned at 71 minutes then he will no be returning - the period of suspension is playing time, so while the clock is off his suspension clock is off as well.
Wasn't there a law ruling that said teams could bring back on sin binned players, or make subs at their own penalty?
It's late, I'll look for it tomorrow.
1. A penalty kick is awarded to White team. Before the kick is taken, can
White team make a substitution? (If so, we assume that the substitute can
take the penalty kick.)
2. A penalty kick is awarded to White team. Before the kick is taken can a
previously sin-binned White player return; given that the 10 minutes have fully
elapsed? (If so, we assume that the returning player may take the penalty
kick.)
The Designated Members have ruled the following in answer to the question
raised:
A substitution can only be made when the ball is dead. A referee must not let
a player rejoin the match until the ball is dead. The ball is dead when the ball
is out of play. This happens when the ball has gone outside the playing area
and remained there, or when the referee has blown the whistle to indicate a
stoppage in play, or when a conversion kick has been taken.
In both cases outlined above, the ball is dead, and therefore the answer to
each question is in the affirmative.
I was always under the understanding that the team in possession may do what they wanted in terms of subbing and if they chose to sub the other team may also.
