他の人を故意に負傷させたので、あなたは攻撃のために起訴される可能性がありますが、実際にあなたに対する告発が実際にどれほど強くなるかは議論の余地があります。誰かがすでにそれで怪我をしているかどうかに依存します
you could be  charged for assault since you knowingly injured another person although it is debatable how strong the charges against you would actually be since the worst thing that could happen would be a broken foot and only if the person kicks the ball really hard and it also depends if someone already injured themselves on it or not
