He’s been away from WWE programming after he suffered a shoulder injury. He was expected to be on the card for John Cena’s last event in December, but was removed because of the ailment.

Sheamus debuted on the main WWE roster in 2009. He quickly became well-received and was the prime villain to face Cena for his world championship at the time. Later, he defeated Cena to win the WWE Championship, making him the first Irish-born WWE champion in the company’s history.

He held the title three more times in addition to being a five-time tag team champion, three-time United States champion and the winner of the King of the Ring, Money in the Bank ladder match and Royal Rumble.
