Triple H says The Undertaker wasn't necessarily on board right away with appearing at WrestleMania XL.

The Undertaker retired after facing AJ Styles in a Boneyard Match at WWE WrestleMania 36. Since then, after 30 years of a WWE career, Undertaker has remained firm in his retirement. He did get physical at WrestleMania XL, however. He Chokeslammed The Rock and proved to be the deciding factor in helping Cody Rhodes win the Undisputed WWE Universal Championship from Roman Reigns that Sunday night.

Appearing on The Roommates Show with Brunson and Josh Hart, Triple H revealed that it wasn't easy getting Undertaker to agree to his appearance, saying it even took a phone call from The Rock to help convince him.

"It took us forever to get him to do that thing. A lot of that stuff comes together in the tail end. When I first called him for it, he's like, 'I don't know. I don't think I want to do it.' I'm like, '80,000 people are going to go absolutely insane.' It took us a little bit. Rock had to call him. Everybody had to call him to get him to finally acquiesce to do it. When he retired, he sort of wanted, 'I'm just done.' He didn't come out with the hat and jacket. The hat and jacket are retired. 'I'll come out as me, but I'm not coming out as Undertaker.' He just wanted it to be over."
