Tomlin has come under major scrutiny after appearing to step on the field to impede Jacoby Jones, who was close to returning a punt for a touchdown but the coach's foot caused him to change direction and he was brought down.
He told reporters: "My actions on that play are embarrassing. I take full responsibility for my actions. I understand there are repercussions that come with a blunder of that nature.
"With my position comes the charge of preserving and protecting the integrity of football. That play jeopardized the integrity of the NFL from a competition standpoint. That's a mistake on my part."
Tomlin has yet to be punished by the NFL as they are continuing to review the play.
