Coach interference during play

[Nevadaref]

"Assistant coach gets tech in unusual sequence.Colorado assistant coach Kim English removes a water bottle from the court during play, gets hit in the head with the ball and receives a technical foul."

ESPN video clip needed.

Don't know what else can be done after the fact since he clearly interfered with play inbounds.

If an official is able to observe the water bottle get knocked onto the court and halt play before the coach interferes would a technical foul still be warranted or a bench warning? POI on the missed FT still has to be AP, which is annoying. Unfortunate situation to deal with.
