Was Cory Hill released from the UFC shortly after he suffered a leg injury because the UFC was reluctant to pay insurance?

McGregor suffered a shin injury, and I looked it up to compare it with past shin injuries.
The case of Cory Hill was particularly prominent.

Cory Hill appears to have been terminated by the UFC due to a leg injury.

Of course, the UFC fully funded his surgery, but...
Did UFC fire Cory Hill because they didn't want to pay for his insurance as an employee after the injury?

According to the article, Coryhill moved with his family because he could not afford to pay for treatment when he had no job and no income.

At the time, Cory Hill had a record of 2 wins and 2 losses, but he didn't seem to have enough to release him.

Tim Sylvia, Diego Sanchez, Spencer Fisher, etc.
Players who broke up with the UFC suffered from aftereffects years later.

I understand a little bit that the UFC doesn't take care of all these people.

But in the case of Cory Hill... I think this is definitely unreasonable.

Q: Why did the UFC terminate its contract with Cory Hill at the time?
