WWE superstar Roman Reigns is finally speaking out about why he decided to pull out of "Wrestlemania 36" ... saying straight up, "I had to make a choice for me and my family."
The 34-year-old -- a 2-time cancer survivor -- was supposed to wrestle Goldberg for the WWE Universal Championship during the April 4 and 5 event ... but ultimately decided it wasn't worth the risk to his health.
According to ProWrestlingSheet, Reigns told WWE he's immunocompromised from the cancer fight -- and didn't feel comfortable performing with the looming threat of COVID-19.
