It sounds like a Przewalski’s horse. I checked all of the links for additional pictures but the one was it.
I would love to see it sans mud. The articles said it was brown with zebra stripes(primitive markings) on the legs.

We’ll have to wait till they wash it............
Most “wild” horses today, such as the American mustang or the Australian brumby, are actually feral horses descended from domesticated animals that escaped and adapted to life in the wild. The Przewalski’s horse may never have been domesticated and has long been considered the only true wild horse extant in the world today. However, a 2018 DNA study suggested that modern Przewalski’s horses may descend from the domesticated horses of the Botai.[7]
