The former NRL player suffered a horrific spinal injury for Hull in the English Super League in January 2020.
Masoe's doctors said he would never walk again, but four months later - after radical spinal surgery - he took his first steps.
"The battle has just begun and the challenges ahead I am ready for it, it's going to be tough," Masoe said.
Fifteen months later, the 31-year-old is a shadow of his former 1.9-metre and 120-kilogram build.
"It's not just a physical [game], it's a mental game," Masoe said.
