But speaking on New Heights, external, the podcast he co-hosts with his brother Jason, Kelce said: “I can’t get that fired up to the point where bumping coach and it’s getting him off balance and stuff.
“It came in a moment when we weren’t playing very well and I wasn’t playing very well.
“It’s definitely unacceptable and I immediately wished I could have taken it back. Coach Reid actually came right up to me after that and didn’t even have harsh words for me.”
Jason Kelce, who played two seasons under Reid with the Philadelphia Eagles, said his brother had “crossed the line”.
“The yelling in his face, too, was over the top,” Jason Kelce added on Wednesday’s podcast.
“I think there are better ways to handle this, retrospectively.”
Kelce, who is in a relationship with pop star Taylor Swift, said Reid would have had every right to respond to his outburst with physicality.
He added: “I’m a passionate guy. I love coach Reid. He knows how much I love to play for him, how much I love to be a product of his coaching career.”
