Here's one to sort out (NFHS)

[PiggSkin]

The way I see it, R would be best served to decline K's Face mask foul... Then R keeps possession of the ball, its Face mask is enforced from the R 35-->R20... R77's head slap is enforced (R20-->R10), followed by K68's USC (R10-->R25)... 1-10@25 for R...

If R accepts K's Facemask, the fouls offset... R77's dead ball foul is enforced (K40-->R45)... This gives K a first down... K's USC is enforced (R45-->K40)... Chains are then set... 1-10@K40 for K...

Either way, R77 is ejected, and K68 probably is too...
