The 27-year-old was not in the Magpies team that shocked Tottenham 1-0 the past weekend.
He has often found himself criticized by supporters for a lack of work ethic. But Shelvey wants to set the record straight.
He said to reporters: "I get labelled lazy, maybe because of my body language and I'm quite a laid-back character.
"You can run 15k if you want, but at the end of the day, I'm a footballer.
"Do you see Gazza running 15k? Do you see people like that?
"I'm not comparing myself to them but I understand that football is changing and evolving, and I am evolving with it, but I get labelled lazy.
"People can say what they want. I'm the one that goes out there and trains every day as hard as I can."
