Thoughts on what might’ve happened to this buck..

I don't think coyotes prey on larger deer. Could possibly be gored by another buck though that's an odd area to be gored.

He will either die from infection or get weak and coyotes will end it.

Several years ago I took my son to a friends place to shoot an axis doe. As we were fixing to leave, one finally showed up at the feeder and my boy ended up using the hood of the truck as rest for his rifle. Long story short, he made a bad shot. I initially though he had missed, but we approached the feeder to make sure. When we got there, I noticed what appeared to be wet clumpy grass on the ground but no blood. We began following the wet grass clumps and soon determined he had deeply grazed the abdomen of the doe. As the doe bounded off, the weight of her stomach finally pushed through the incision the bullet made. We soon found her intestines around a tree which she had wrapped them around. We found her dead not far from there. Very sad, and I was upset at my son, but we all have made bad shots at some point in our lives. Lesson learned for him. Also that was the first animal I think I have not had to gut. (Well partially anyway.) The buck in this picture could have been grazed by a bullet or a top strand of barb wire. You may keep an eye open for buzzards just in case! I'm not sure how he would survive that wound. That gut is sure to get caught on something and pulled out further. Or pulled out by coyotes.
