well what i understand if he trying to win the ball in the pa then pen and only a yellow cared any other foul then pen and redNo, he clearly does not. As others have said, you probably need to replay it on a bigger screen. Even if he did though, getting the ball does not preclude committing a foul when your careless and/or reckless follow-through takes the player's legs out from under him.
Depends on the exact manner of the "taking out" of the player. If it's SFP, as far as I understand, it should still be a red.
