UFC fighter Israel Adesanya's rough few days in New York got even worse Monday at JFK Airport.

Adesanya lost his belt to Alex Pereira during the main event of UFC 281 Saturday at Madison Square Garden.

And he was arrested Tuesday at about 1:57 p.m. after TSA found him in possession of metal knuckles at a screening area, the Port Authority Police Department confirmed to Fox News Digital.

Metal knuckles are illegal in the state of New York.
