Ineligible man downfield

[seanireland]

this was tough for me too because the jargon used by the seasoned officials was confusing. i am not sure when the ref would really have time to call an ineligible downfield, but as a U a few times, this is what i've learned so far. U keys the center and the interior line.
Look at numbers first. ineligible numbers are 50-79 inclusive. they are ineligible by number. they get to block two yards if engaged with a defender who was on the LOS (i.e. ENZ).
look for tight end also. Check the wingman on that side to see if he is covered and therefore ineligible. If wings arms are by his/her side with a flanker on that side, then tight end is ineligible.
there are always at least five ineligibles on offense, but a covered tight end will also be ineligible. U goes to the LOS on pass read to verify the status of those ineligibles at the time the pass crosses the NZ.
