Miami Dolphins offensive tackle Jonathan Martin might not return to the team.
The Dolphins issued a statement Sunday afternoon confirming league and team probes into allegations of misconduct that led to Martin walking out of the team facility this week.
"We received notification today from Jonathan's representation about allegations of player misconduct," the statement read. "We are taking these allegations very seriously and plan to review the matter further. We have also reached out to the NFL and asked them to conduct an objective and thorough review. As an organization, we are committed to a culture of team-first accountability and respect for one another."
ESPN reported earlier Sunday that Martin, who left the Dolphins last week amid reports of bullying from teammates, specifically fears retribution from guard Richie Incognito.
The Dolphins are expected to place Martin on the non-football injury list as soon as Tuesday, according to the NFL Network's Ian Rapoport.
ESPN's Adam Schefter reported that Martin was intimidated by Incognito into paying $15,000 toward a trip to Las Vegas. Martin did not go on the trip but still surrendered the money.
Incognito took to Twitter on Sunday, writing "I want my name CLEARED." He took direct aim at Schefter, writing: "Stop slandering my name. You hide behind "sources" who are not man enough to put their name behind the BS you report."
