Kingfisher took the second-half kickoff and drove 55 yards in nine plays, with Newton hitting Blair on a 14-yard scoring pass. Landon Nault quickly intercepted quarterback Michael McMullen, then threw a 24-yard halfback pass that Blair juggled, but held on to, in the end zone, making it 21-0 less than five minutes into the third quarter.
Blair was injured while playing defense on Heritage Hall's next series and was on crutches after the game, but Myers said the injury likely was a hip pointer and Blair should be OK.
A pair of short touchdown runs by Newton put Kingfisher ahead 35-0 with 10:24 left. Newton carried 15 times for 47 yards and completed 7-of-13 passes for 87 yards, while Nault had 18 carries for 54 yards.
McMullen hit Dominique James on a 25-yard touchdown pass with 2:39 left to allow Heritage Hall to avoid the shutout. McMullen finished 12-of-22 passing for 98 yards.
