This is not an issue in our house... DD7 actually errs far on the other side, where she's so worried about hurting other kids that she plays too soft and is ineffective.
But in this situation, the way I'd handle it is by putting her on the bench for a few minutes and making her watch the other kids play without her for a bit, while explaining that if she can't play the game the right way, she can't play it at all. Then I'd allow her to get back in the game, and if the problem continues... in the house she goes.
Another way you could deal with this is by showing him how his style of play affects others by modeling it yourself. You or another adult could bring him out on the field and school him. Once he gets good and worked up about it, ask him how he feels.
