Satterley started wrestling professionally in the mid-2000s, debuting in his native United Kingdom in 2004 but soon going international with appearances in Pro Wrestling Guerrilla in the United States and Dragongate in Japan.

Satterley signed a deal to join WWE in 2012 and debuted under the ring name Adrian Neville in 2013. He participated in Royal Rumble for the first time in 2016 and captured the cruiserweight championship in 2017.
