I'm with Verile - we've got first touching by K wherever he touched the ball to bat it, don't we? Since R hasn't committed a foul after touching the ball, and there's no penalty being accepted, they'd have the right to take the ball at the spot of the touch, which they'd do in play 1. In play 2, since the loose ball is still a kick, and it went into the end zone, they'll pass on the first touching and take the ball at their own 20.
