"It's kind of a tender topic," Newton said light-heartedly on the NFL Network's "NFL AM" show on Thursday in New York City.
Newton went on to say in a playful way, "He hurt my feelings, and I think so highly of Mr. Kaepernick."
So will there be an answer to the mock that Kaepernick made after running for a touchdown in a 23-10 victory over the Panthers at Bank of America Stadium?
"It will," said Newton, who will appear with Kaepernick on Feb. 17 at The Cartoon Network's fourth annual Hall of Game Awards. "It will."
Newton couldn't get the Panthers to the Super Bowl, but he was in NYC on Thursday making the rounds as part of the Super Bowl week festivities.
One of his stops was on ESPN Radio's "SVP and Russillo" show.
Among the topics was whether he really changed much in 2013 from his first two seasons when the Panthers were a combined 13-19 to how much winning had to do with the perception he'd changed.
"Winning has a lot to do with it," Newton said. "No one likes to lose, including myself. When losing is the reason, who knows what the scrutiny will come after. There are a lot of things that get swept under the rug if you're winning ... your demeanor, your approach to the game, are you even taking it serious.
"I've been questioned with a lot of things, some of it fair, some of it not fair. But that's the day and time that we live right now."
Newton said the way the year ended for a Carolina team that went from 1-3 to 12-4 and NFC South champions "was a salty ending to a great season."
"It is up to us as a team, as a coach, as an organization to get better from it," he said. "It will be shame on us if we don't make the best of our situation leading up to next season."
