COLLEGE FIASCO? NOT QUITE CLEAR, BUT . . . (AMENDED)

Question:
At a Division III college women’s soccer game, a Red team player tried to keep the ball from going out of bounds. The line judge ruled that she had stepped out while touching the ball and put up his flag indicating that the Blue team should have the throw in. Play continued, however, and the center judge did not see the line judge’s flag, even after 10-15 seconds when the line judge was vigorously waving the flag. After about 20 seconds, he put his flag down as play continued on the field. About 25-30 seconds after the out of bounds was initially called, the Blue team scored a goal. The Red team coach protested that the goal should be disallowed because of the out of bounds call.

What is the correct call in this situation?

(In the game, the center judge did disallow the goal and gave the Blue team the throw in.)

Answer (September 25, 2012):
Nothing you have described about the woman who stepped outside the field is illegal. Nothing you have described about the woman who stepped outside the field was illegal. The “line judge,” actually called an assistant referee, was TOTALLY INCORRECT, even under college rules, and so was the”judge,” actually called the referee, provided the ball remained on the field during this action. It is not an offense to leave the field during the course of play to keep the ball in play inside the boundaries of the field. The correct call would have been no call at all, based on the scenario you gave me.

AMENDMENT:
The questioner now informs me that the ball did indeed leave the field. In that case, the AR was correct in waving the flag and the referee was correct in disallowing the goal.
