Here's one to sort out (NFHS)

[Theisey]

Try this.
Live ball fouls on both K and R.
R's foul could be a PSK foul. It turns out that when the down ends, it is be a PSK foul.

Here's one possible outcome. I can see another, but someone else can post that.

R declines K's FM foul and K accepts R's FM foul.

Spot the ball at the R-20 as the end of kick was the R-35.

Now, we have a pair of dead ball fouls on both R and K that looks clear that the order of occurance is known.
Since the chains have not been set and the ready for play not given, we enforce them both in order. First is R's foul, take the ball to the R-10 ( half distance applies), then enforce K's foul which places the ball at the R-25.

R77 is DQ'd from the game. A DQ might be considered for K68 is this were his second UC foul. I would not consider K68's actions to be fighting.

So, R's ball 1/10 @R-25
