Speaking to Sky Sports after the weigh-in, Taylor wasn't surprised by Catterall's actions during the face off.
"He put his hands on me," Taylor told Sky Sports .
"I knew I'd get a rise out of him. I knew I'd get a reaction.
"Tomorrow he will be flat on his back."
Catterall meanwhile dismissed any notion that Taylor had suceeded in the mind games ahead of this fight.
"No definitely not [he isn't under my skin]. I saw him marching over," Catterall said.
"I have more support here than he does!
"I have worked every aspect of my game for tomorrow night. It's about keeping a cool head in a hot kitchen."
