Jahrus added the wrestling pioneer was an inspiration in “many other” areas of life including upholding family values.
He added: “He was many things: a hard-working father, a caring brother, a supportive uncle, and a proud grandfather.
“He was a cherished friend to many, a loving family member whose warmth and kindness knew no bounds, and an inspiration to countless individuals.
“His legacy will continue to inspire and uplift future generations, reminding us of the impact one person’s life can have on so many. Rest in love Uncle Sika. #wildsamoans #halloffamer #sikaanoai.”
Sika’s son Roman has not been seen since his Wrestlemania loss to Cody Rhodes, and the late wrestler was also father to the late WWE wrestler Matthew Anoaʻi.
Sika’s achievements in the ring include becoming a three-time WWE tag team champion.
He kicked off his wrestling career in 1973, joining WWE seven years later and last wrestled for them in 1988.
His legacy lasted a lifetime for fans, with the Wild Samoans inducted into the WWE Hall of Fame in 2007.
Reigns is yet to comment publicly on the passing of his father, but fans have flooded social media with tributes including one who hailed him as “the real Tribal Chief”.
