Trainers and seasoned fighters were not used to 6 ft 7in boxers who possessed such speed and athleticism, and as such it proved difficult to find suitable opponents.
His break out fight came in 2015, when he challenged Hungarian Zoltan Csala for the vacant IBO Inter-Continental Heavyweight title.
Cornish dominated Csala and won the fight via a technical knockout in the fourth round.
Cornish remained largely absent from the public eye following the Joshua fight, but since regrouped in 2016 with two points victories in bouts fought in Scotland.
He has a tattoo on his chest, saying "Alba gu bràth,"[5] which is a Scottish Gaelic phrase used to express allegiance to Scotland as it means 'Scotland forever'.
