Defense Holding- Spot of enforcement
 

2nd and 10 at B's 40.

Quarterback A10 scrambling; and B44 holds A88 at B's 30 while running a pass route.

(a) A10 sacked at B's 45. spot of enforcement??

(b) A10 throws an imcomplete pass. spot of enforcement??

In NF rules, the spot on both is going to be the previous spot (or LOS).

Peace

what if the holding is on a back behind the line of scrimmage. where is the spot of enforcement??

if the qb is facemasked then it is the end of the run. qb sacked fro 10 yard loss and facemasked during the tackle then it is 5 or 15 from the end of the run and repeat the down.

is it because the foul is past the line of scrimmag/previous spot that we use it as the basic spot

A) It is a running play, and since the penalty on the defense is enforced from the basic spot--which is the end of the run.

B) Loose ball play, enfore from the previous spot.

A. End of run (45).

B. previous spot.

Enforcement of defensive fouls is always from the basic spot (exception is roughing the passer).

This is not a loose ball play so it MUST be a running play. Basic spot for running plays is the end of the run. Enforce this foul from the B-45, 2nd and 5 at the B-35. Quarterback could have helped himself out by fumbling the ball :)

This is a loose ball play so basic spot is the previous spot. 1st and 10 at B's30.

Canadian Ruling
 

In both cases, apply the 10 yards from the PLS, and unless yards were gained, repeat the down.
