An NFL assistant coach resigned Monday morning after a video of him allegedly snorting a white powdered substance surfaced on Sunday.

Chris Foerster, who has coached the offensive line of the Miami Dolphins for the last two seasons, addresses a camera and speaks of missing the person watching the video, and states that he is snorting the substance before heading to a meeting.

“I am resigning from my position with the Miami Dolphins and accept full responsibility for my actions,” Foerster said in a statement released Monday. “I want to apologize to the organization and my sole focus is on getting the help that I need with the support of my family and medical professionals.”
