Miami Dolphins head coach Joe Philbin met with offensive tackle Jonathan Martin last week and said on Monday that no accusations of misconduct were raised until Sunday, when Martin's representatives contacted the team.
Philbin said he had enough information to make a decision as of Sunday to suspend offensive guard Richie Incognito, but would not discuss details of conversations with either player.
Philbin and owner Stephen Ross agreed to request an objective NFL investigation into the matter.
"I take this responsibility very seriously," Philbin said at his weekly press conference on Monday. "If the review shows this is not a safe atmosphere, I will take whatever steps necessary to make sure it is."
Incognito is unlikely to return to the team.
Martin, who left the Dolphins last week amid reports of bullying from teammates, specifically feared retribution from Incognito, according to ESPN, and shared the content of the text and voice messages, with family, the team and the NFL.
According to multiple reports, Incognito sent intimidating text messages to Martin, including one in which Incognito refers to Martin, who is biracial, as a "half-(racial slur)" and also includes disturbing threats against him and his family.
