If the ball would not necessarily have been awarded to the defending team, then the team with the excluded player starts with a player in the re-entry area. For example:
a. If a shot is taken at the end of the period and the ball goes out of bounds, not touched by any player, the teams start even up at the beginning of the next period.
b. If a shot is taken at the end of the period and tipped out any field player, the teams start even up at the beginning of the next period.
