Former WWE star Big Cass, appearing under the name W. Morrissey, short for his real name of William Morrissey, made his Impact Wrestling debut at Rebellion 2021. Morrissey appeared as a replacement for the injured Eric Young for Violent By Design in an eight man tag. Young made it clear that Morrissey was not a full member of the team. It is not clear if Morrissey is with the company full time going forward.
Morrissey wrestled for WWE from 2013-2018, mainly teaming with Enzo Amore. The two of them regularly challenged for various Tag Team Titles but Morrissey never won any titles in the company. Since leaving the company, Morrissey has taken a hiatus from wrestling before returning to the independent circuit earlier this year. This is his first appearance with Impact Wrestling.
It was a heck of a debut. Check out how Morrissey looked in the ring:
