5 WWE Stars who only entered the Royal Rumble once

#1. Enzo Amore (Royal Rumble 2017)

Enzo Amore made his Royal Rumble debut back in 2017, which was the final year that there was just one Royal Rumble match on the show. Amore entered at number 27 and was eliminated after just 18 seconds by Brock Lesnar.

At the time, Enzo and Cass were climbing through the ranks in WWE and were seen as the future of the tag team division, but this fell apart in the year to come, since both men were let go in 2018.

Big Cass himself kicked off the 2017 Royal Rumble match alongside Chris Jericho but wasn't able to go the distance, and was eliminated by Braun Strowman inside 10 minutes.

Enzo and Cass later went on to feud with each other before Cass suffered a legitimate knee injury and ended their on-screen rivalry.

Amore and Big Cass have since gone on to work together outside of WWE following their controversial releases from the company, but neither men are expected to make their return to WWE as part of any future Royal Rumble matches.
