Buffalo Bills wide receiver Zay Jones got into a bizarre naked struggle with his brother -- who's also in the NFL -- and it ended in a bloody mess ... with Zay in handcuffs.
TMZ Sports obtained this video of the crazy fight that went down Monday night in a downtown L.A. apartment building. Zay is stark raving nude while grappling with his brother -- Cayleb Jones of the Vikings.
You can hear Zay yelling, "I'm going to fight for Jesus" ... and according to witnesses, Cayleb was trying to stop him from jumping out a 30th floor window.
