A "covered up" player is one who begins a play as an eligible receiver (both by position and number) on the end of the line who is rendered ineligible, either deliberately or unintentionally, by the actions of another player, who takes a wider position on the same side of the line.

The "covered" player, although still eligible by number, would no longer be eligible by position as he is no longer on the end of the line.

ah ok that makes sense.

From this year's Points of Emphasis -

The old idea of "hitting until the whistle" is passé. It must be remembered by coaches and officials that the whistle is only confirmation that a play is over. The play kills itself.<style> Font Definitions */ @font-face {font-family:Verdana; panose-1:2 11 6 4 3 5 4 4 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:536871559 0 0 0 415 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-parent:""; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman";} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> </style><!--[if gte mso 10]> <style> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} </style> <![endif]--><style>

Waltjp:
I am not sure I understand what you are attempting to say? :confused:
While I agree with this years point of emphasis, it has nothing to do with "No live ball foul causes the ball to become dead"

ART. 6 . . . Pass eligibility rules apply only to a legal forward pass. The
following players are eligible pass receivers:
a. All A players eligible by position and number include those who, at the time
of the snap, are on the ends of their scrimmage line or legally behind the
line (possible total of six) and are numbered 1-49 or 80-99. (See 7-2-5a
EXCEPTION)
b. All A players become eligible when B touches a legal forward pass.
c. All B players are eligible.
d. A player who is eligible at the start of the down remains eligible throughout
the down.

Yeah, perhaps poorly worded, but it does. The question was whether to blow the whistle when you see a foul. The answer, of course, is no.

Not even in the case of the hideout play (simulated substitution to get the defense to ignore a receiver)?

Robert-
I see where you are going now!
No, you do not have rule support to shut down a "hideout play" or any play for that matter. That being said however you do have rule support to enforce the penalty as a previous spot foul.
Rule 9-6-4...It is illegal participation:
b. To use a player, replaced player, substitute, coach, trainer, or other attendant in a substitution or pretend substitution to deceive opponents at or immediately before the snap or free kick.
PENALTY: 4b-f (live-ball, previous spot) - (S28) - 15 yards

Wrong!!!
 

AJMC- (aka AlinupstateNY)
You'll excuse me if I take the opportunity to point out WHAT YOU WROTE is poorly worded and misleading, and therefore, by NFHS definition, renders itself to be false and incorrect!

Source 2008 NFHS Rule Book Page 82 Football Fundamentals VII. Passes
1.A player who is eligible at the start of a down remains eligible throughout the down.

It is just not possible for a player who "...begins a play as an eligible reciever..." to then become "...rendered ineligible..."

Congratulations, you are absolutely correct, I blew right by Football Fundamental VII and used a poorly worded, and possibly misleading phrase, to try and explain a basic concept. Good thing you were there to avoid a calamity.

I understand what you are saying but some of it could be a little misleading. The person being covered may not be there in error. As someone else noted, some teams line up this way intentionally for running plays. There is nothing wrong with that. Also, he may be covered up because he's supposed to be in the back field but lined up wrong (rather than the wide-out).

I would simplify the explanation as a player with an eligible number on the line of scrimmage who is not on the end.

CANADIAN ANSWER:

Eligible:

• 1-39 or 70-99 and the widest player on the line, or any player in the backfield, and isn't an ineligible receiver (see definition) or
• 40-69, has reported to the Referee, and is not in an ineligible position

Ineligible:

• 40-69, or
• other # and reported as ineligible
