At a game the coach says that they have a play they may run. The tackle will not be covered on the LOS and will eligible by position (end of line) but ineligible by number (#78). At the snap, the player will delay and then go backwards and will receive a backwards pass from the QB around 5 - 7 yards behind the LOS. Is this a legal play? I can find numbering and position restrictions on a forward pass but can't locate anything on a backwards pass. Thank you.
