Not sure what others are seeing, but B5 only tries to play football. He charges forward after the snap, then loses his feet and goes to the ground. He wants to get up, but A65 slaps B5’s head around while B5 is sitting there. Yeah, B5 grabs A65’s leg, but A65 breaks away and then blatantly knees B5 in the head.
I’ve got nothing on B5, and a flagrant personal foul on A65. A65 gets ejected.
