PLAYER MISSING AT END OF KICKS FROM THE PENALTY MARK

Question:
In the taking of KFTPM to decide a tournament winner the teams make 10 goals each. The 11th player makes a goal but now the opponent’s 11th player is missing.

What should happen now?

USSF answer (July 2, 2011):
Provided the team’s 11th player was on the field at the beginning of the kicks from the penalty mark, this portion of the Advice to Referees applies:

19.2 PLAYERS LEAVING THE FIELD DURING KICKS FROM THE PENALTY MARK
Once the procedure of taking kicks from the penalty mark has begun, players are not permitted to leave the field, even if they have already taken a kick. If a player leaves the field and is not available to take the prescribed kick (either for the first time or subsequently), the referee can declare the missing player no longer eligible and then proceed with the kicks from the penalty mark without him/her. A full report regarding the situation must be submitted.
