A 20-year old man died last week after falling ill during a training session at the wrestling school run by WWE Superstar Seth Rollins ... this according to local reports.

WKBW reports that the student -- named  Jonah Snyder -- died Thursday after training at Black & Brave Wrestling Academy with eight other people.

The Rock Island County Coroner says trainers instructed Snyder to sit down after he fell ill, but symptoms got worse and 911 was called. When paramedics arrived, Jonah went into cardiac arrest.

He was pronounced dead at the hospital.

Snyder's cause of death is unclear at this time. An autopsy done Friday was inconclusive and Moline Police are investigating the death. Our condolences go out to his family and friends.
