He is well known in the industry for a gruesome in-ring injury which occurred when Gary Jay ripped a turnbuckle out of his mouth, tearing his cheek open.

That same month Parnell participated in a Triple Threat match against Dave Vaughn and Brandon Gallagher.

[9] In 2019, Parnell, inspired by his love of heavy metal music and 1980s wrestling icons like The Road Warriors and Sting, reinvented himself as Warhorse, a very metal misfit with face paint that likes to headbang, yell, and "Rule Ass".

[12] Warhorse has been active in Game Changer Wrestling as part of the tag team "Warhausen" with fellow wrestler Danhausen.

[13] On July 29, 2020, Warhorse made his debut for All Elite Wrestling (AEW) on Dynamite where he challenged Cody Rhodes for the TNT Championship in a losing effort.
