On 19 February at Elimination Chamber, Sheamus attacked World Heavyweight Champion Daniel Bryan after Bryan retained his title, thus challenging Bryan for and winning the World Heavyweight Championship on 1 April at WrestleMania XXVIII, in a record 18 seconds. On 6 April episode of "SmackDown", Sheamus lost to Alberto Del Rio in a non-title match by disqualification, thus earning Del Rio a future title match and starting a feud between the two. On 29 April at Extreme Rules, Sheamus successfully defended the World Heavyweight Title against Bryan in a two out-of-three falls match. Sheamus then returned to his feud with Del Rio which eventually began to include Chris Jericho and Randy Orton. The rivalry between them culminated in a fatal-four way match for the World Heavyweight Championship on 20 May at Over the Limit, where Sheamus pinned Jericho to retain the title. Del Rio earned another title shot on 25 May episode of "SmackDown", but suffered a concussion a week before their match at No Way Out and was subsequently replaced by Dolph Ziggler; Sheamus retained the title in their match. Sheamus went on to retain the title against Del Rio and Ziggler over the next few months, including at Money in the Bank, SummerSlam, and Night of Champions. On 28 October at Hell in a Cell, Sheamus lost the World Heavyweight Championship to Big Show, ending his reign, which was the third longest in the title's history, at 210 days.
