This exact situation occurred to my girls' squad Tuesday vs. Spartanburg 1 min. into the match. My left back stepped to block a shot taken from inside the box, she had her arms extended away from her body and the ball hit her arm. A penalty kick was awarded and converted. 1 minute into the match and we're down 1-0 not the way you want to start a match.

At half time I pointed out... As a defender stepping to block a shot, it's so important to keep your arms close to your body, especially inside the box. Intentional or not I believe the correct call was made.
