Man Shot At Jorge Masvidal's Miami Home, Fighter Not Present At Time

A man was shot at Jorge Masvidal's Miami area home Thursday afternoon following a verbal altercation ... before being transported to the hospital with at least one gunshot wound to the arm area, TMZ Sports has learned.

The recently retired UFC superstar was NOT home at the time of the incident ... and was not involved in the incident in any way, according to officials.

However, Jorge's dad, Jorge Masvidal Sr., is currently in custody, where he is being interviewed by police.

Miami-Dade PD tell us they received a call around 3 PM. When they arrived, EMTs were already on the scene "rendering aid to an adult male who was shot in his upper extremities."

Cops say the victim told them he was "involved in an argument that escalated when the subject produced a firearm and shot him."

The cause of the argument, and who was involved, is currently unclear ... though police tell us the parties know each other.

We're told the victim was transported to a local hospital where he is now in stable condition.

38-year-old Masvidal recently retired from the UFC ... but is still one of the most popular fighters in the world.

Jorge is scheduled to have a Gamebred Bareknuckle event in South Florida on Friday night.
