NFL: Cowboys’ Jones reignites protest conversation.

DAVIE, Fla. — Miami Dolphins coach Adam Gase says offensive line coach Chris Foerster seemed so focused on the team that he would often be at work by 4 a.m. Then a video surfaced that rocked Foerster’s reputation and cost him his job.

The 55-year-old assistant coach resigned Monday, apologized and said he was seeking medical help after a video on social media appeared to show him snorting three lines of white powder at a desk.

Hours after the video was posted on Facebook, Foerster announced his departure in a statement released by the team.

“I am resigning from my position with the Miami Dolphins and accept full responsibility for my actions,” he said. “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.”

The 56-second video was first posted to the Facebook page of model Kijuana Nige on Sunday night. It’s unclear when and where the video was shot, and it was deleted Monday. The NFL said it was reviewing the matter. The video appears to show Foerster and the powder on the desk. The man is holding a rolled-up $20 bill in his right hand and appears to adjust the camera with his left hand.

“Hey babe, miss you, thinking about you,” he says. “How about me going to a meeting and doing this before I go?”

He then snorts the substance into his nose though the $20 bill and notes “those big grains falling” as residue lands on the desk.

“What do you think, I’m crazy?” Foerster asks after snorting the second line. “Ah, no, babe.

“It’s going to be a while before we can do this again … ” he says, “But I think about you when I do it. I think about how much I miss you, how high we got together, how much fun it was. So much fun.”

Before snorting the final line he says, “Last little bit before I go to my meeting.”
