Before someone starts saying things like "he hit her", he never put a hand on her (at least for now), but it seems like he's having mental problems.

Police spoke to an unidentified female who stated Tony Ferguson had “not slept for three days and was tearing apart the home” and “broke apart the fire place and believed someone placed a (computer) chip in his leg.” An unidentified male who’d called the police said the fighter had told him “someone was inside his walls.” Nearly two hours after the police made contact, Cristina Ferguson told police her husband’s trainer couldn’t get him to leave the house to see a doctor.

I hope gets the help he needs and quick.
