Lorn being more athletic and used to getting out of the way of hooves when breaking horses, and wrestling cows/bulls at rodeos, took the hit without much problem as he moved in such a way that the hit didn't do much damage.  He reached a boot out to trip the man as the guy came through with the hit aiming to let the man fall in the dirt.  He had likely been in more fistfights back home than this guy had here in town.  Lorn's cowboy had had not even fallen off his head yet.
