I didn't see it coach...

[LMSANS]

This is my first year officiating football.

I was the HL in a Pop Warner Jr Pee Wee game (Fed rules) last night. 3-man mechanics This is what happened:

A 1-10 @ A30. A10 runs towards my side, he is tripped up at A30 and lands on A32. I mark the spot and the U is waiting at the hash for the ball, when we look and B33 has the ball at A28. Neither of us saw how or when the ball changed hands. R came over from the other wing and wanted to give the ball to B. U and I said since we didn't see the ball come lose, it stays A ball. We "won" the argument, but after the game R insisted we should have given the ball to B.

The official running the clock in the press box later told us, he saw B take the ball after A was down, so we made the right call.

Any opinions?
