I figured he would be OK, seen several hit like that,they get worse cuts on a barb wire fence,
I have seen several in the last few years with one leg missing ,suppose it was cut of with a hay mower or hung in fence, a friend of mine killed one on my place 3 or 4 years ago had 3 legs,wonder what kind of blood trail that left,
he seemed no worse for wear and was 2 or 3 years old,the leg had hoof like material on the bottom and was healed just fine. I accused him of killing cripple deer.
They are tough and anything short of a vital or gut shot they usually make it fine if left along and they get the bleeding stopped.
