He changed his name in 2019 to honor his uncle, boxing trainer Emanuel Steward, explaining that he was like a father to him.
Steward worked at his uncle's Kronk Gym, where he first met Tyson Fury in 2010.
After Emanuel Steward died in 2012, SugarHill worked with some of his uncle's former fighters, including Adonis Stevenson, Anthony Dirrell and Charles Martin.
At the time, Steward's existing clients were less prominent fighters such as Shohjahon Ergashev and Apti Davtaev.
The trilogy fight ended in a knockout win for Tyson Fury culminating in the end of a three-year rivalry and resulting in Steward getting his first heavyweight title defense as a head coach.
