William Morrissey is an American professional wrestler, best known for his time in WWE, under the ring name Big Cass. He is also well known for his tag team with Enzo Amore, whom he teamed with from 2013 to 2017. Together, they won the NXT Year-End Award for Tag Team of the Year in 2015. In 2018 he was released from his WWE contract. According to Sports Illustrated, Morrissey’s release was due to behavioral issues, including public intoxication during a WWE tour and disobeying orders from Vince McMahon.
On December 8, 2018, Morrissey suffered a seizure at a House of Hardcore event while at his merchandise table. He was treated by medical personnel while Tommy Dreamer and Bubba Ray Dudley were by his side. He was responsive but eventually taken to the hospital. Arndt expressed support for Morrissey on Twitter.
