DAVIE, Fla. -- Miami Dolphins offensive line coach Chris Foerster resigned Monday after a video surfaced on social media of him snorting a white powder.

Foerster said in a statement that he will seek professional help.

"I am resigning from my position with the Miami Dolphins and accept full responsibility for my actions," Foerster 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."

This was Foerster's second stint with the Dolphins and second season with the team, which also released a statement.

"We were made aware of the video late last night and have no tolerance for this behavior," the team said. "After speaking with Chris this morning, he accepted full responsibility and we accepted his resignation effective immediately. Although Chris is no longer with the organization, we will work with him to get the help he needs during this time."

Dolphins head coach Adam Gase said Monday he was made aware of the video around 10:45 p.m. ET on Sunday night. General manager Chris Grier called Gase to offer details and discuss the next move.

Gase said he was surprised and disappointed.

"I don't think I can say what my reaction was," Gase said.

Gase said he had a brief conversation Sunday night with Foerster, who apologized to him and resigned Monday morning. Foerster was "mad at himself," according to Gase. As of Monday, the Dolphins do not know how recent the video is or the location. The team will continue to investigate. Gase said he is aware of how the video surfaced.

"It's not a good situation," Gase said. "It's not something you expect. But things happen sometimes that you don't anticipate and you have to deal with it. It's not fun, especially when you're close to somebody. But you gotta take the next step and move on because we're going to play on Sunday."

In the video, Foerster is seen using a $20 bill to snort the powdery substance off a table while speaking into the camera, saying, "Hey, I miss you. ... Thinking about you. ... How about me going to a meeting and doing this before I go."

"I saw no signs of this happening. I'm still shocked by it to be honest," backup offensive tackle Eric Smith said Monday. "Still to this moment, it's been about 12 hours since I seen the video and I'm still in shock. I have no true expression or emotion that I can express for the situation right now. It's a lot to take in. You don't see this every day. Definitely not with every team."

Foerster, who turns 56 on Thursday, was one of the highest-paid assistant coaches in the NFL, at a salary valued between $2.5 million and $3 million a year.

"Since I've been around him, he's always been a guy that just put his head down and work," Gase said. "He was here are 4 in the morning, worked as hard as he could for us. It is what it is."

Gase said the team has not yet thought about a potential replacement for Foerster.

"Anytime you lose a really good coach, it's not ideal," Gase said. "But it's the reality. We'll figure out a way. We will show up next week and do our thing."

This marks the second time in recent years that a Dolphins offensive line coach has been involved in controversy. The Dolphins fired offensive line coach Jim Turner in 2014 after Ted Wells' investigation into the bullying scandal in the team's locker room in which Jonathan Martin was harassed by his teammates on the offensive line.
