FLORHAM PARK, N.J. — Muhammad Wilkerson and Sheldon Richardson on Wednesday both addressed the reasons they were benched by coach Todd Bowles for the first quarter of the Jets’ loss to Miami last Sunday.

Wilkerson, who signed a five-year, $86-million contract extension in the offseason, said he had been late to meetings and missed a walk-through before the Week 7 game against Baltimore.

“Those actions are unacceptable,” he said. “I definitely feel that, as a leader on this team, I need to do better. I respect the coaches, I respect everyone in this building. I take responsibility for my actions.”

Asked why he was coming forward now when he was reluctant to discuss the discipline on Sunday, Wilkerson said: “This is a distraction, clearly. I don’t want to be a distraction. That’s not me. It’s not my character. It’s not me as a teammate. Moving forward, it won’t be an issue for me.”

Richardson said he “overslept 20 minutes” on Friday.

“I’m not a regular at missing meetings,” Richardson said. “Coach Bowles is a disciplinarian. That was my sentencing right there. It has been blown way out of proportion. I know me missing the first quarter isn’t blown out of proportion, but it was one meeting.”
