Potential Shot clock violation?

[Nevadaref]

If the shot clock horn sounds while the ball is in the air, and the try then fails to contact the ring, the shot clock violation must be whistled no matter which team gains control of the miss.

However, if the try is an airball and the opposing team gains control prior to the shot clock expiring, as was the case that you describe, then the shot clock is properly reset upon the establishment of possession and the game should not be stopped by the officials.
