Goofy situation

[daveg144]

A coach calls timeout with 15 seconds remaining and the score tied to set up a last second shot for the home team. The table informs the official that there are no timeouts remaining so a technical foul is issued. The opponents go the other end of the floor to shoot 2 technical fouls. Both were made.

The ball is taken out-of-bounds at half court and a lob pass is thrown to the center for a dunk where he is fouled and given a chance to take the visiting team to a comfortable five point lead with 9 seconds remaining. The defending center has just fouled out committing his fifth foul of the game.

Suddenly the horn blows as the official is reporting the foul with the table indicating that there was a mistake with the previous timeout and the coach did have one timeout remaining.

Where do we go from here?
