"I just want to put out there, there was no fight at half time," Deeney, 32, told beIN Sports.
"It's 2020. We don't do that anymore. You know, certainly with all the cameras and everything, you'd certainly see a lot more if that was the case.
"The gaffer didn't put his hands on anybody. He was just frustrated and had a firm talking to, so no one was fighting, no one was punched, no one was even tickled. I don't know, whatever way there was: no hands thrown, let's just put it that way."
Deeney said the timing of Pearson's dismissal caught him off guard.
"It's strange obviously, we didn't see it coming. I think you get to a point in football where you're not surprised anymore but I would say that this one certainly, you know, took me back a bit," Deeney said.
