MIAMI (AP) — The Miami Dolphins suspended guard Richie Incognito late Sunday for misconduct related to the treatment of teammate Jonathan Martin, who abruptly left the team a week ago to receive help for emotional issues.

“We believe in maintaining a culture of respect for one another,” the Dolphins said in a statement released shortly before midnight, “and as a result we believe this decision is in the best interest of the organization at this time. … We will continue to work with the league on this matter.”

The move capped a bizarre day for the Dolphins, even though their players were off. First the team released a statement saying Martin had not complained to the organization about bullying by other players. Hours later, the Dolphins said they and the NFL were investigating allegations of misconduct made Sunday by representatives of Martin.
