How Do You Penalize Chipping by the Offense?

[Ed Hickland]

Know we went through this sometime in the past and I seem to remember one association or state (commonwealth as in Kentucky, Mass. uses NCAA) that had a good solution.

A player running for a touchdown when A78 decides this is a good time to give opponent B78 a nice unsuspected de-cleater fifty yards away from the ball while it is still alive. Personal foul. How do you penalize if the result of the play is a touchdown? What if it results in a tackle at the one yard line still in A's possession?

Could someone refresh my memory? Thanks.
