When asked about the incident last May wherein Incognito allegedly harassed a woman at a charity golf tournament, Philbin said the team took "immediate action," but didn't say what that action was.
"We were made of aware of the situation, we took immediate action," Philbin said. "Any club action we took against any player would remain private."
The Dolphins coach declined to comment when asked by a reporter why Incognito was kept in a leadership role after the incident.
The harassment incident was just the latest news to spiral out of the Incognito-Jonathan Martin situation. Philbin said he believes Martin could have come to him if he felt uncomfortable in the locker room.
"I believe I'm approachable to the players," Philbin said.
Philbin also reiterated that the team is working with the NFL on its investigation.
"We're all committed to getting to the bottom of this," he said.
