What is the ruling on a sacrificial ram for Eid that is healthy but has a hernia?

The sacrificial animal must be free from the defects stipulated in the Hadith (definition): "Four [types of animals] are not permissible as sacrifices: the one-eyed animal whose one-eyedness is obvious, the sick animal whose sickness is obvious, the lame animal whose lameness is obvious, and the emaciated animal that has no marrow." This includes anything similar to these or more severe. If the aforementioned hernia is obvious and a defect, then it falls under the jurisdiction of defects that prevent the sacrifice from being valid.
