Something I have never had before

[JTRICE]

Team A is at the line shooting a 1-1.
Team B member steps into the lane early.
I give the "Delayed lane violation" signal.
Ball bounces around the rim and falls off.
My partner blows the whistle.
We get together and he has a pushing foul on the defense.

Not that this is a hard one to call.....but.... I have never seen it before.

We cleared the lane and let Team A shoot the 1-1 and then we went the other way and let team B shoot a 1-1 with players along the line.
