Dont get too discouraged yet.. Go back in the morning to where you jumped him and see if you can find more blood. It sounds to me like the arrow had good blood. This might be one of those situations where he bedded down wounded and would have expired if you hadn't jumped him. I may have done the same thing and only waitedan hour or sothough if I found good blood. Good luck though finding him tomorrow. Take a couple buddies out to help you look!
