I think it was probably my mistake. I had put him in the trailer, then at the last minute decided to take Rocky, since I wasn't takeing Harley, and Jenny was going to be there.
Rocky usually goes in first then Rusty. I think since Rocky was with him and I unloaded Rocky first, Rusty got in a hurry to get out and started backing before I could unhook him. Of course it took me a few seconds to think what to do, I was way up in the corner of the trailer while he was doing his think and it was kind of hairy:). When I released the panic snap he just fell out of the trailer.
He looks fine this morning. I don't think the head bump was what was so sore. I think the check straps on the halter pulled tight on his jaws or something. He kept acting like something in his mouth was hurting. Turning his head sideise and chewing on the bit, but not really opening his mouth all the way, and slobbering.
I'll ride him this morning and see what he does. But he looks like his old self now. After I tied him up to the trailer, he stood very very quiet which is not like him. Something wasn't right. Hopefully it was just a temporary soreness.

Probably gave him a headache!
Glad it's just a minor one and doesn't need the vet out.
