Last second shot with light (NFHS)

[RookieDude]

Last week...Boys NFHS District game...winner to state.

2.6 seconds left in regulation...Team A down by 2 with a throw-in at the endline.
Team A gets three trys at the basket with the last try in Player A1's hand as the horn goes off. C opposite table blows whistle and waves off shot as the ball goes in the basket and the light (yes, light) turns on LATE.

Team B and fans rush the floor thinking they have gone to the state playoffs. Team B coach is hollering for a T because the game "is not over, the light went on as the ball went in."

Officials get together with the table and decide (just as the C had) the horn went off in the player's hand...and the light has nothing to do with the last shot. The officials leave the confines of the court to a chorus of boo's from Team A's fans.

Team A's athletic director came into the officials locker room, very respectfully, and asked if he could protest the game...due to a rules violation concerning the light on the backboard.

Whatta ya got?
