Welcome to BYC. I'm sorry about your rooster. Even though he has been raised with his brother, integrating back into the flock may be hard. If at all possible, set his cage up inside the coop or run, so that he is still part of the flock.
Can you feel a broken bone? Hopefully it is only a sprain.
Good luck!
