DAVIE, Fla. -- The Miami Dolphins are in the middle of an important investigation by the NFL. At the center of it is the offensive line, the unit that worked closely with suspended guard Richie Incognito and embattled right tackle Jonathan Martin.

Several Dolphins offensive linemen confirmed Wednesday that they had interviews with the NFL. These are the players who best know Incognito, Martin and the relationship between them that eventually led to bullying and harassment allegations by Martin.

“Everything went very well. So we will see how it goes,” Dolphins center Mike Pouncey said of the investigation. "We were in there for a while. They asked a bunch of questions. … It seemed like a long time but it probably wasn't. They got all the questions they wanted to get out of us and we gave them all the trustful answers."

Left tackle Bryant McKinnie joined the team in October from Baltimore. He didn’t know either party well, but said he hasn’t been afraid to voice his opinion on the situation.

According to McKinnie, investigators wanted to pick his brain as a veteran who has played on three different teams and been in various locker rooms. McKinnie estimated his interview lasted about 30 minutes.

"There was four people in there and two people asking questions," McKinnie said. "They’re just trying to gather knowledge from everybody on what really happened and go from there."

Dolphins right tackle Tyson Clabo also has been vocal and supportive of Incognito. However, Clabo was more tight-lipped about what went on behind closed doors when he met with the NFL.

"Yeah, I did that. They asked us to respect the process of the investigation and to not really go into the details about it," Clabo said. "So I did my time up there and that’s really all I’m going to say about it."

Pouncey, who has spent time with Incognito since the suspension, said he believes the full truth will come out at the conclusion of this investigation.

The Dolphins (5-5) are still in the playoff hunt and have tried to stay focused with a big game upcoming at home against the Carolina Panthers (7-3).

"I feel like we’re all at ease now," Pouncey said. "Now we can just focus straight on football. That’s the most important thing, that we can focus on football so we can win games."
