The continuity of downs was broken when R touched the ball beyond the NZ. K was then eligible to possess it. When K picked it up behind the NZ, the ball remained live, and K could do what they wanted to do with it, including passing it. K threw and incomplete forward pass, so Team K was still in possession at the end of the down. The result would be K 1/10 @ K-35 after enforcing the foul for the intentional grounding at the end of the run. The loss of down aspect would have no effect since a new series was awarded. The clock would start on the snap since a new series is awarded following a legal kick.
