Thank you so much for all the advice! Yes, I did fix the bridge so he doesn't get injured or any other snakes for that matter! He was certainly moving normal when he went under the house. He wasn't too happy, but he was moving great! I am sorry, but I didn't even think to take pictures of his wound area! I'm usually good about that! I just paniced when I saw he was hurt. I am keeping an eye out for him everyday, but I am sure he has chosen another location around my home to hide! Again, thanks for all the advice!
