While catching a fast moving cricket ball, a fielder in the ground gradually pulls his hand backward because by doing this, he increases the time in which the velocity of ball will become zero. Thus, the rate of change of momentum will be large and less force will be exerted by the ball on the hand of the fielder. Hence, he will not get injured by the ball.
