Kick play

[bossman72]

4th and 8 from K's 30. R33 holds K12 beyond the NZ during the kick. The kick is rolling and is first touched by K at the K 45. R44 picks up the ball and runs it back to the K20 where he fumbles and K recovers.

If K declines the penalty, R can take the result of the play or take the ball at the spot of first touching, correct?

If K accepts the penalty, that's where I'm a little more hazy. If it's accepted, R cannot take it at first touching and this would not be PSK enforcement since K is next to put the ball in play, correct? So it would be enforced from the previous spot and replay the down (if the penalty didn't make the line to gain)?

Thanks!
