This is an example of a pushing foul on a rebound. In this example after an attempted 3 point shot Black 9 has front position on White 5. As White 5 is crashing the boards for the rebound he realises the ball is rebounding further. In an attempt to secure the rebound he uses two hands and pushes Black 9 in the back to stop him from getting the rebound. This is a pushing foul on White 5.
