Ref's Challenge #2

Progress Indicator:
Question 1 of 10

1.  A defender makes no attempt to head the ball but intentionally backs into an opponent causing him to fall. What is the correct decision?

Choices:

1. There is no foul because the player is on the ground. Therefore play should continue.
2. The foul is tripping with the body and direct-kick should be awarded, or a penalty-kick if the foul happened in the penalty-area.
3. The foul is obstruction and an indirect-kick should be awarded.
