To T or Not to T

[Zoochy]

During the 1st quarter A10 is beckoned into the game. Before the ball is in-bounded by Team A, the scorers table informs the officials that A10 IS NOT in the scorebook. The official asks if there is a roster that lists the players with their numbers. The table provides the official with the game roster that has both team listed with players and numbers. A10 is listed on this game roster. The official has the scorer add A10 to the scorebook.
How does the game resume?
