Are you allowed to push with your shoulder in soccer?

Well it's not a "non-contact" sport per se, and most referees will overlook a bit of bustling between to players to get the ball, but if someone shoulder charges full force, and it really is just intended to batter the other player out of the way that would be a foul.

The general rule is that if you get the ball, the tackle's legitimate... if you're just out to hurt another player or get them out the way, that would be a foul and probably a red card. Black10 says: Have you ever heard the saying, "shoulder up"? Yes, in most case you do use a lot of your shoulder to throw your opponent off the ball or to win the ball. Yet make sure not to throw elbows that is harmful and can cause the other player to get hurt and possibly yourself. Other then that have fun get physical and play to your best. So basically, "Not all wars have ceasefire, just half time."
