Ineligible Receiver Downfield

[Mike246]

For some reason I have a mental block with this rule, but the wording seems
a bit confusing:

"... a penalty that is called when a forward pass is thrown and an ineligible receiver is beyond the line of scrimmage without blocking an opponent at the time of the pass."


1. Ball is snapped and as the QB is dropping back, the left offensive tackle runs downfield. At seven or eight yards, he throws a block on the strong safety. The QB throws a pass to a flanker on the right side.

2. Ball is snapped. QB drops back. Left tackle drive blocks the defender over him and pushes him back four or five yards. The QB then throws a pass downfield.

Are both of these examples penalties?
